Introduction to APPCORE Routine APIs

This chapter provides you with specifications for calling many Oracle E-Business Suite APIs from your PL/SQL procedures. Most routines in the APPCORE library are described here. Some APPCORE routines are described in other chapters (for example, the APP_SPECIAL routines are described in the chapter "Controlling the Toolbar and the Default Menu"). The routines described in this chapter include:

APP_COMBO: Combination Block API
APP_DATE: Date Conversion APIs
APP_EXCEPTION: Exception Processing APIs
APP_FIELD: Item Relationship Utilities
APP_FIND: Query Find Utilities
APP_ITEM: Individual Item Utilities
APP_ITEM_PROPERTY: Property Utilities
APP_NAVIGATE
APP_RECORD: Record Utilities
APP_REGION: Region Utilities
APP_STANDARD Package
APP_WINDOW: Window Utilities

APP_COMBO: Combination Block API

Use APP_COMBO to control navigation in combination blocks.

APP_COMBO.KEY_PREV_ITEM

Variable	Description
Summary	`procedure APP_COMBO.KEY_PREV_ITEM;`
Location	APPCORE library
Description	Call this procedure in the KEY-PREV-ITEM trigger to provide the standard behavior when back-tabbing from the first item in a record. This procedure ensures that the cursor automatically moves to the last item of the previous record. See: Combination Blocks

APP_DATE and FND_DATE: Date Conversion APIs

You can use the APP_DATE and FND_DATE package utilities to format, convert, or validate dates. The packages are designed to hide the complexities of the various format masks associated with dates. These routines are particularly useful when you are manipulating dates as strings. The routines are designed to handle the multilingual, flexible format mask, and Y2K aspects of these conversions.

The APP_DATE routines are located in the APPCORE library and can be called from forms and other libraries, except for libraries that are attached to APPCORE, such as the CUSTOM library. For code in the CUSTOM library and other libraries attached to APPCORE, use the APP_DATE2 package in the special APPCORE2 library. The APP_DATE2 package is equivalent to APP_DATE, with the same routines and routine arguments.

The FND_DATE package is located in the database. You can call FND_DATE routines from SQL statements or other database packages. Many of the routines are in both the APP_DATE and the FND_DATE packages.

List of Date Terms

Because a date can be expressed in many different ways, it is useful to define several date-related terms that appear in the following APIs.

Variable	Description
Form date field	A text item (in a form) that has a data type of "Date".
Form datetime field	A text item (in a form) that has a data type of "Datetime".
Form character field	A text item (in a form) that has a data type of "Char".
PL/SQL date	A PL/SQL variable declared as type "Date". Such a variable includes both date and time components.
User date format	The format in which the user currently sees dates in forms.
User datetime format	The format in which the user currently sees dates with a time component in forms.
Canonical date format	A standard format used to express a date as a string, independent of language. Oracle E-Business Suite uses YYYY/MM/DD HH24:MI:SS as the canonical date format.

Warning: The APP_DATE and FND_DATE routines make use of several package variables, such as canonical_mask, user_mask, and others. The proper behavior of Oracle E-Business Suite depends on these values being correct, and you should never change any of these variables.

APP_DATE.CANONICAL_TO_DATE and FND_DATE.CANONICAL_TO_DATE

Variable	Description
Summary	`function APP_DATE.CANONICAL_TO_DATE( canonical varchar2) return date;`

Variable	Description
Location	APPCORE library and database (stored function)

Variable	Description
Description	This function takes a character string in the canonical date format (including a time component) and converts it to a PL/SQL date. If APP_DATE.CANONICAL_TO_DATE fails, the routine displays a message on the message line and raises form_trigger_failure. If FND_DATE.CANONICAL_TO_DATE fails, the routine raises a standard exception from the embedded TO_DATE call but does not return a message.

Variable	Description
Arguments (input)	canonical - The VARCHAR2 string (in canonical format) to be converted to a PL/SQL date.

Example 1

declare
  hire_date varchar2(20) := ‘1980/01/01‘;
  num_days_employed number;
begin
  num_days_employed := trunc(sysdate) -
app_date.canonical_to_date(hire_date);
  message(‘Length of employment in days: ‘||
  to_char(num_days_employed));
end;

Example 2

Description	This function takes a character string in the user date format and converts it to a PL/SQL date. If APP_DATE.DISPLAYDATE_TO_DATE fails, the routine displays a message on the message line and raises form_trigger_failure. If FND_DATE.DISPLAYDATE_TO_DATE fails, the routine raises a standard exception from the embedded TO_DATE call but does not return a message. In previous releases this function was named APP_DATE.CHARDATE_TO_DATE (that name has been retained for backwards compatibility).
Arguments (input)	chardate - The VARCHAR2 string (in the user date format) to be converted to a PL/SQL date.

Location	APPCORE library and database (stored function)
Description	This function takes a character string in the user datetime format and converts it to a PL/SQL date. If APP_DATE.DISPLAYDT_TO_DATE fails, the routine displays a message on the message line and raises form_trigger_failure. If FND_DATE.DISPLAYDT_TO_DATE fails, the routine raises a standard exception from the embedded TO_DATE call but does not return a message. In previous releases this function was named APP_DATE.CHARDT_TO_DATE (that name has been retained for backwards compatibility).
Arguments (input)	charDT - The VARCHAR2 string (in the user datetime format) to be converted to a PL/SQL date.

APP_DATE.DATE_TO_CANONICAL and FND_DATE.DATE_TO_CANONICAL

Variable	Description
Summary	`function APP_DATE.DATE_TO_CANONICAL( dateval date) return varchar2;`
Location	APPCORE library and database (stored function)
Description	This function converts a PL/SQL date to a character string in the canonical date format. The entire time component is retained.
Arguments (input)	dateval - The PL/SQL date to be converted.

Example

from emp ...

APP_DATE.DATE_TO_DISPLAYDATE and FND_DATE.DATE_TO_DISPLAYDATE

Variable	Description
Summary	`function APP_DATE.DATE_TO_DISPLAYDATE(dateval date) return varchar2;`
Location	APPCORE library and database (stored function)
Description	This function converts a PL/SQL date to a character string in the user date format. Any time component of the PL/SQL date is ignored. In previous releases this function was named APP_DATE.DATE_TO_CHARDATE (that name has been retained for backwards compatibility).
Arguments (input)	dateval - The PL/SQL date to be converted.

Example

declare
  my_displaydate varchar2(30);
  my_dateval date;
begin
  my_displaydate :=
  app_date.date_to_displaydate(my_dateval);
end;

APP_DATE.DATE_TO_DISPLAYDT and FND_DATE.DATE_TO_DISPLAYDT

Variable	Description
Summary	`function APP_DATE.DATE_TO_DISPLAYDT(dateval date) return varchar2;`
Location	APPCORE library and database (stored function)
Description	This function converts a PL/SQL date to a character string in the user datetime format. Any time component of the PL/SQL date is preserved. In previous releases this function was named APP_DATE.DATE_TO_CHARDT (that name has been retained for backwards compatibility).
Arguments (input)	dateval - The PL/SQL date to be converted.

Example

declare
  my_displaydt varchar2(30);
  my_dateval date;
begin
  my_displaydt :=
  app_date.date_to_displaydt(my_dateval);
end;

APP_DATE.DATE_TO_FIELD

Variable	Description
Summary	`procedure APP_DATE.DATE_TO_FIELD( dateval date, field varchar2, datetime varchar2 default ‘DEFAULT‘, date_parameter boolean default FALSE);`
Location	APPCORE library
Description	This procedure copies a PL/SQL date into a form field, form parameter, or global variable. Use this routine instead of the COPY built-in routine when date processing is required. When copying a value into form fields where the datatype is Date or Datetime, this procedure uses the appropriate internal mask to maintain the datatype. When copying a value into form fields where the datatype is Char, by default this procedure applies the user datetime format if the field is long enough to hold it; otherwise this procedure applies the user date format. When copying a value into global variables or form parameters, by default this procedure assumes a datatype of Char and applies the canonical date format, ignoring any time component. Use the date_parameter argument to override this behavior.
Arguments (input)	dateval - The date to be copied. field - The name of the field to which the date is copied, including the block name. datetime - Use to override the default rules for determining date or datetime format. The default value is ‘DEFAULT‘. Specify ‘DATE‘ or ‘DATETIME‘ to force the copied value to have the date or datetime formats. Typically, you would use this argument to force the use of the datetime format in global variables and parameters, and for forcing use of the date format in character items that are longer than the datetime user mask. date_parameter - Use this argument only if you are copying the value to a date parameter (with the date data type). If this argument is set to TRUE, the value is copied as a date value instead of as a character value.

Example

Replace the following code:

COPY(to_char(my_date_value, ‘DD-MON-YYYY {HR24:MI:SS}‘,‘my_block.my_date_field‘);

with the following code:

app_date.date_to_field(my_date_value, ‘my_block.my_date_field‘);

APP_DATE.FIELD_TO_DATE

Variable	Description
Summary	`function APP_DATE.FIELD_TO_DATE( field varchar2 default NULL, date_parameter boolean default FALSE) return date;`
Location	APPCORE library
Description	This function takes a value from a form field, form parameter, or global variable and returns a PL/SQL date. Use this routine instead of the NAME_IN built-in routine when date processing is required. When copying a value from form fields where the datatype is Date or Datetime, this procedure uses the appropriate internal mask to maintain the time component. When copying a value from form fields where the datatype is Char, this procedure applies the user datetime format if the field is long enough to hold it; otherwise this procedure applies the user date format. When copying a value from global variables or form parameters, by default this procedure assumes a datatype of Char and applies the canonical date format, with or without the time component depending on the current length. If APP_DATE.FIELD_TO_DATE fails, the routine raises a standard exception from the embedded TO_DATE call but does not return a message.
Arguments (input)	field - The name of the field from which the date should be copied, including the block name. date_parameter - Use this argument only if you are copying the value from a date parameter (with the date data type). If this argument is set to TRUE, the value is copied from the parameter as a date instead of as a character value.

Example

Replace the following code:

to_date(NAME_IN(‘my_block.my_date_field‘), ‘DD-MON-YYYY {HH24:MI:SS}‘);

with the following code:

my_date = app_date.field_to_date(‘my_block.my_date_field‘);

APP_DATE.VALIDATE_CHARDATE

Variable	Description
Summary	`procedure APP_DATE.VALIDATE_CHARDATE( field varchar2 default NULL)`
Location	APPCORE library
Description	This procedure checks to see if a character value in a given form field (datatype Char) is a valid date by parsing it with the user date format. If the conversion to a date with no time component fails, the routine displays a message on the message line and raises form_trigger_failure. If the conversion succeeds, the routine copies the converted value back into the field to ensure display consistency.
Arguments (input)	field - The name of the character field to be validated, including the block name. If no field name is passed in, the procedure uses SYSTEM.CURSOR_ITEM.

APP_DATE.VALIDATE_CHARDT

Variable	Description
Summary	`procedure APP_DATE.VALIDATE_CHARDT( field varchar2 default NULL)`
Location	APPCORE library
Description	This procedure checks to see if a character value in a given form field (datatype Char) is a valid datetime string by parsing it with the user datetime format. If the conversion to a date with a time component fails, the routine displays a message on the message line and raises form_trigger_failure. If the conversion succeeds, the routine copies the converted value back into the field to ensure display consistency.
Arguments (input)	field - The name of the character field to be validated, including the block name. If no field name is passed in, the procedure uses SYSTEM.CURSOR_ITEM.

FND_DATE.STRING_TO_DATE

Variable	Description
Summary	`function FND_DATE.STRING_TO_DATE( p_string IN VARCHAR2, p_mask IN VARCHAR2) RETURN DATE;`
Location	Database (stored function)
Description	This function converts a character string to a PL/SQL date using the given date format mask. This function tests all installed languages, if necessary, to find one that matches the language-dependent fragments of the given string. Use this routine when you need to convert character string data to dates and are unsure of the language used to store the character date. This function returns NULL if the string cannot be converted. There is no error message. Your code must test for a NULL return value and handle the error as appropriate. Language is important if the mask has language-dependent fragments, as in the format mask DD-MON-RRRR, where the "MON" fragment is language dependent. For example, the abbreviation for February is FEB, but the French abbreviation is FEV. The language testing order of this function is: Language indicated by the setting of "NUMERIC DATE LANGUAGE". Current (default) database language. The "Base" language of the Oracle E-Business Suite installation (where the INSTALLED_FLAG column of the FND_LANGUAGES table is set to "B"). Other installed languages, ordered by the NLS_LANGUAGE column of the FND_LANGUAGES table (where the INSTALLED_FLAG column is set to "I").
Arguments (input)	p_string - The character string to be converted. p_mask - The format mask to use for the conversion, such as DD-MON-RRRR.

FND_DATE.STRING_TO_CANONICAL

Variable	Description
Summary	`function FND_DATE.STRING_TO_CANONICAL( p_string IN VARCHAR2, p_mask IN VARCHAR2) RETURN VARCHAR2;`
Location	Database (stored function)
Description	This function is identical to FND_DATE.STRING_TO_DATE except that this function returns a character string in the canonical date format instead of returning a PL/SQL date.
Arguments (input)	p_string - The character string to be converted. p_mask - The format mask to use for the conversion, such as DD-MON-RRRR.

APP_ITEM: Individual Item Utilities

This section describes utilities for managing your items individually.

APP_ITEM.COPY_DATE

Variable Description

Variable	Description
Summary	`procedure APP_ITEM.COPY_DATE(` `date_val varchar2 item_name varchar2);`
Description	Use this procedure to copy a hardcoded date value into a field. This routine does the copy in this way: `copy(to_char(to_date(‘01-01-1900‘, ‘DD-MM-YYYY‘), ‘DD-MON-YYYY‘), ‘bar.lamb‘);`

Summary

procedure  APP_ITEM.COPY_DATE(

date_val  varchar2
			item_name varchar2);

Description

Use this procedure to copy a hardcoded date value into a field. This routine does the copy in this way:

copy(to_char(to_date(‘01-01-1900‘, ‘DD-MM-YYYY‘),
               ‘DD-MON-YYYY‘), ‘bar.lamb‘);

Variable	Description
date_val	A character date, expressed in the format ‘DD-MM-YYYY‘
item_name	The name of the item to copy the value into, expressed as block.item.

APP_ITEM.IS_VALID

Variable	Description
Summary	`procedure APP_ITEM.IS_VALID( val varchar2 dtype varchar2 default ‘DATE‘); function APP_ITEM.IS_VALID( val varchar2 dtype varchar2 default ‘DATE‘) return BOOLEAN;`
Description	Use this routine with fields that are of character datatype but contain data in the format of a date, number or integer. The procedure raises an error if the value is not in a valid format for the specified datatype. The function returns TRUE if the value is in the correct format, otherwise FALSE

Variable	Description
val	Value to be checked
dtype	Datatype value should use: DATE, INTEGER, or NUMBER.

APP_ITEM.SIZE_WIDGET

Variable	Description
Summary	`procedure APP_ITEM.SIZE_WIDGET( wid_name varchar2. max_width number default 20);`
Description	This procedure reads the current label for the specified widget and resizes the widget to fully show the label (used to ensure proper size for a translated label). It will not make the widget any larger than the maximum width specified, to prevent overlapping or expansion beyond the edge of the screen. Call this procedure only for check boxes in single-record formats, buttons and radio groups.

Variable	Description
wid_name	Name of the widget in block.field syntax
max_width	The maximum size to make the widget, in inches

APP_ITEM_PROPERTY: Property Utilities

These utilities help you control the Oracle Forms and Oracle E-Business Suite properties of your items.

APP_ITEM_PROPERTY.GET_PROPERTY

Variable Description

Summary

function  APP_ITEM_PROPERTY.GET_PROPERTY(
       item_name varchar2, 
			property number) 
			return number;

function  APP_ITEM_PROPERTY.GET_PROPERTY(
			item_id item, 
			property number)
			 return number;

Description This function returns the current setting of an item property. It differs from the Oracle Forms‘s get_item_property in that it returns PROPERTY_ON or PROPERTY_OFF instead of TRUE or FALSE.

Variable	Description
item_name	Name of the item to apply the property attribute to. Specify both the block and item name. You can supply the item_ID instead of the name of the item.
property	The property to set.

See: Setting Item Properties.

APP_ITEM_PROPERTY.SET_PROPERTY

Variable Description

Summary

procedure  APP_ITEM_PROPERTY.SET_PROPERTY(
       item_name varchar2, 
			property varchar2, 
			value number);

procedure  APP_ITEM_PROPERTY.SET_PROPERTY(
			item_id item, 
			property varchar2,
			value number);

Description This procedure sets the property of an item. You should never use the Oracle Forms built-in SET_ITEM_PROPERTY to set the field properties DISPLAYED, ENABLED, ENTERABLE, ALTERABLE, INSERT_ ALLOWED, UPDATEABLE, NAVIGABLE, REQUIRED, and ICON_NAME directly. Use APP_ITEM_PROPERTY.SET_PROPERTY instead.
APP_ITEM_PROPERTY.SET_PROPERTY remaps some properties to do other things like change visual attributes. Also, there are some properties that APP_ITEM_PROPERTY provides that native Oracle Forms does not.

Variable	Description
item_name	Name of the item to apply the property attribute to. Specify both the block and item name. You can supply the item_ID instead of the name of the item.
property	The property to set.
value	Either PROPERTY_ON or PROPERTY_OFF, or an icon name (to change the icon property).

See: Setting Item Properties

APP_ITEM_PROPERTY.SET_VISUAL_ATTRIBUTE

Variable Description

Summary

procedure  APP_ITEM_PROPERTY.SET_VISUAL_ATTRIBUTE(

item_name varchar2, 
			property number 
			value number);

Description This procedure is no longer used. All colors are set as part of the Oracle Look and Feel (OLAF).

APP_NAVIGATE: Open a Form Function

Use this utility instead of FND_FUNCTION.EXECUTE to open a form function where you want to reuse an instance of the same form that has already been opened. Use FND_FUNCTION.EXECUTE for all other cases of opening forms and functions.

APP_NAVIGATE.EXECUTE

Variable Description

Summary

procedure APP_NAVIGATE.EXECUTE( 		
		function_name	in varchar2, 		o
		pen_flag 	in varchar2 default ‘Y‘, 		
		session_flag	in varchar2 default ‘SESSION‘, 		
		other_params	in varchar2 default NULL, 		
		activate_flag	in varchar2 default ‘ACTIVATE‘, 		
		pinned	in boolean  default FALSE);

Description

This procedure is similar to FND_FUNCTION.EXECUTE, except that it allows a form to be restarted if it is invoked a second time. For example, if form A invokes function B with this procedure, then at a later time invokes function B again, the same instance of form B will be reused (and form B would be restarted using any new parameters passed in the second call to APP_NAVIGATE.EXECUTE). This functionality is useful where you have a form B built to appear as a detail window of another form (A), and you want the "detail window" to reflect changes in the "master window". In contrast, FND_FUNCTION.EXECUTE always starts a new instance of a form.
Only a function that was previously invoked using this call is a candidate for restarting; a function invoked with FND_FUNCTION.EXECUTE cannot be restarted if later a call is made to APP_NAVIGATE.EXECUTE.
Multiple forms can share the same target form. For example, if form A invokes function B with APP_NAVIGATE.EXECUTE, and then later form C also invokes function B, the current instance of form B will be restarted.
APP_NAVIGATE.EXECUTE and FND_FUNCTION.EXECUTE store the position and size of the current (source) window in the following global variables so that the target form can access them:

global.fnd_launch_win_x_pos
global.fnd_launch_win_y_pos
global.fnd_launch_win_width
global.fnd_launch_win_height

The intended usage is so that the target form can be positioned relative to the current window of the calling form. When calling APP_NAVIGATE.EXECUTE, these values are available when the target form is opened the first time; it is not valid to refer to them during the RESTART event.
Using APP_NAVIGATE.EXECUTE requires special code in the target form (form B) to respond to the APP_NAVIGATE.EXECUTE call appropriately. The target form must contain a user-named trigger called RESTART, as well as the required calls to APP_STANDARD.EVENT in the WHEN-NEW-FORM-INSTANCE and WHEN-FORM-NAVIGATE triggers. When a form is reused with APP_NAVIGATE, APPCORE will:

Issue a do_key(‘clear_form‘) in the target form. This fires the same logic as when the user does Edit->Clear->Form. This is done to trap any pending changes in the target form.
If that succeeds, then all form parameters in the target form are repopulated (parameters associated with the function called by APP_NAVIGATE, as well as values in the other_params argument specifically passed in by APP_NAVIGATE).
User-named trigger RESTART in the target form is executed.

A good coding technique is to place all logic that responds to parameter values in a single procedure and have your WHEN-NEW-FORM-INSTANCE and RESTART triggers both call it. You may also want to add code called from the WHEN-NEW-FORM-INSTANCE trigger in the target form that checks the variables set by FND_FUNCTION.EXECUTE or APP_NAVIGATE.EXECUTE to indicate the position of the source form. You can then use these values to set the position of the target form relative to the source form.

Arguments (input) function_name - The developer name of the form function to execute.
open_flag - ‘Y‘ indicates that OPEN_FORM should be used; ‘N‘ indicates that NEW_FORM should be used. You should always pass ‘Y‘ for open_flag, which means to execute the function using the Oracle Forms OPEN_FORM built-in rather than the NEW_FORM built-in.
session_flag - Passing ‘Y‘ for session_flag (the default) opens your form in a new database session, while ‘N‘ opens the form in the same session as the existing form. Opening a form in a new database session causes the form to have an independent commit cycle.
other_params - An additional parameter string that is appended to any parameters defined for the function in the Forms Functions form. You can use other_params to set some parameters dynamically. It can take any number of parameters.
activate_flag - Either ACTIVATE or NO_ACTIVATE (default is ACTIVATE). This flag determines whether the focus goes to the new form (ACTIVATE) or remains in the calling form (NO_ACTIVATE).
pinned - If set to TRUE will open a new instance of the function, never to be reused (the same as FND_FUNCTION.EXECUTE). If set to FALSE will attempt to reuse an instance of the function if it is currently running and was launched via APP_NAVIGATE.EXECUTE; otherwise it will open a new instance.

APP_RECORD: Record Utilities

Following are utilities that interact with a block at the record level.

APP_RECORD.TOUCH_RECORD

Variable	Description
Summary	`procedure TOUCH_RECORD( block_name varchar2 default NULL, record_number NUMBER default NULL);`
Description	Sets the status of a NEW record to INSERT_STATUS. For a QUERY record, the record is locked and the status is set to CHANGED_STATUS. In both cases this flags the record to be saved to the database.

Variable	Description
block_name	The name of the block to touch
record_number	The record that will be touched

APP_RECORD.HIGHLIGHT

Variable	Description
Summary	`procedure APP_RECORD.HIGHLIGHT( value varchar2/number);`
Description	This call changes the visual attribute of the current record by calling the DISPLAY_ITEM built-in for each multirow TEXT_ITEM, LIST and DISPLAY_ITEM of the current record. It will do nothing for items in which the RECORDS_DISPLAYED property is 1. To highlight data, pass ‘SELECTED_DATA‘. To turn off highlighting, pass ‘DATA‘. You can pass the name of any visual attribute you want to apply.

Variable	Description
value	The name of the visual attribute you want to apply. For more information, see the Oracle E-Business Suite User Interface Standards for Forms-Based Products.

Tip: To improve performance for large blocks with many hidden fields, position all hidden fields at the end of the block, and place a non-database item named "APPCORE_STOP" before the hidden items. When APP_RECORD.HIGHLIGHT reaches this field, it stops highlighting.

APP_RECORD.FOR_ALL_RECORDS

Variable Description

Summary

procedure  APP_RECORD.FOR_ALL_RECORDS(
		block_name      varchar2, 
		trigger_name     varchar2);

procedure APP_RECORD.FOR_ALL_RECORDS(
			trigger_name     varchar2);

Description This call executes the specified trigger for every record of the current block or the specified block. If you specify a block, the GO_BLOCK built-in fires. When finished, the cursor returns to the original record and item.
If the trigger fails, FORM_TRIGGER_FAILURE is raised and the cursor is left in the record in which the failure occurred.
You can pass arguments to the specified trigger using global variables simply by setting the global variables before calling this routine.
APP_RECORD.FOR_ALL_RECORDS fires once when there are no queried records.

Variable	Description
block_name	The name of the block to navigate to
trigger_name	Name of the trigger to execute

APP_RECORD.DELETE_ROW

Variable Description

Summary

procedure  APP_RECORD.DELETE_ROW(
			check_delete        BOOLEAN   default FALSE,
			product_name        varchar2  default NULL,
			message_name        varchar2  default NULL);

function  APP_RECORD.DELETE_ROW(
			check_delete        BOOLEAN   default FALSE,
			product_name        varchar2  default NULL,
			message_name        varchar2  default NULL)
			return BOOLEAN;

Description This call provides a generic message to insure that the user really intends to delete the row.
If the function version of this routine is called, it does not delete the row but returns TRUE if the user responds with a confirmation to delete the record and FALSE otherwise. If you have a complex delete, you can first confirm that the user wants to delete the record.
If the procedure version of this routine is called, the record is deleted if the user responds affirmatively. You should provide your own message when there is more than one block that allows delete.

Variable	Description
check_delete	Forces block DELETE_ALLOWED to be checked (optional)
product_name	The product shortname needed if passing your own message. Otherwise a default message will be supplied (optional)
message_name	The name of the message if a product_name is supplied (optional)

APP_RECORD.VALIDATE_RANGE

Variable Description

Summary

procedure  APP_RECORD.VALIDATE_RANGE(
		from_item     varchar2,
		to_item       varchar2,
		range_name    varchar2  default NULL,
		event_name    varchar2  default ‘WHEN-BUTTON-PRESSED‘,
		dtype         varchar2  default ‘DATE‘,
		product_name  varchar2  default NULL,
		message_name  varchar2  default NULL);

Description This call validates a range to assure that the "from" value is less than the "to" value. Call this routine from the WHEN-BUTTON-PRESSED trigger of a Find button, or a WHEN-VALIDATE-RECORD trigger (for example) to verify that any range data entered by the user is valid.
If the range is invalid, the routine attempts to navigate to the beginning of the range. If you call VALIDATE_RANGE from a trigger that does not allow navigation, then provide a range name so that it can be displayed to the user when the default message is displayed.
You should define the range name in message dictionary and pass the message name to VALIDATE_RANGE. When you define your message, you should include a description that lets the translators know that it should be translated the same as the range title.

Variable	Description
from_item	The block.item of the from value
to_item	The block.item of the to value
range_name	Name of the range (optional)
event_name	Trigger name, used to determine if navigation is possible (optional)
dtype	Datatype of the range (NUMBER or DATE, defaults to DATE) (optional)
product_name	The product shortname needed if passing your own message. Otherwise a default message will be supplied (optional)
message_name	The name of the message, if a product_name is supplied (optional)

APP_REGION: Region Utilities

Following are utilities used with alternative regions (for backwards compatibility only; alternative regions have been replaced by tabs).

APP_REGION.ALT_REGION

Variable Description

Summary

function  APP_REGION.ALT_REGIONS(  		
		poplist_name varchar2)   		     
				return BOOLEAN;

Description Takes the values currently in the poplist identified by poplist_name and shows them in LOV ‘appcore_alt_regions‘ (referenced in from APPSTAND automatically). If the user selects a row from the LOV, the corresponding poplist value will be updated and TRUE will be returned; otherwise no changes will be made to the poplist and this will return FALSE. Used for keyboard support of alternative region control.

Variable	Description
poplist_name	The control poplist for an alternative region (‘block.field‘ format).

Example

if APP_REGION.ALT_REGIONS(‘CONTROL.LINE_REGIONS‘) then
    CONTROL.LINE_REGIONS(‘WHEN-LIST-CHANGED‘);

Summary

procedure  APP_STANDARD.SYNCHRONIZE;

Description Dynamic changes to the form can affect which menu items apply, although the state of the menu items is not re-evaluated automatically. If you make a change that affects which items in the toolbar and menu can be used, call this routine, and it re-evaluates the menu and toolbar. (For example, changing the INSERTABLE property of a block, changing the status of a record, etc.)
See: Pulldown Menus and the Toolbar.

APP_STANDARD.PLATFORM

Variable	Description
Summary	`APP_STANDARD.PLATFORM varchar2(30);`
