Descriptive Flex Fields in Custom Forms

Descriptive Flex Fields in Custom Forms


If you are creating a DFF on the custom form for already defined DFF jump to step 4..

Step1: Registering your table(Required in case of the DFF on a custom table)
Use the add_dd package to register the table and the corresponding columns

For sample....

EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'CHN_REP_CODE', 1, 'VARCHAR2', 10, 'N', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'NAME', 2, 'VARCHAR2', 30, 'N', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'LOCATION', 3, 'VARCHAR2', 10, 'Y', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'REGION', 4, 'VARCHAR2', 5, 'Y', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'PRIORITY', 5, 'VARCHAR2', 1, 'Y', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'STATUS', 6, 'VARCHAR2', 1, 'Y', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'EFFECTIVE_DATE', 7, 'DATE', 10, 'Y', 'N');
EXEC ad_dd.register_column('CUSTOM', 'C01_CHN_REP', 'PARENT_CODE', 8, 'VARCHAR2', 10, 'Y', 'N');EXECUTE ad_dd.register_column('CUSTOM', 'C01_CHN_REP','last_update_date', 9, 'DATE', 10, 'N'



Step2:Check whether all the columns are registered or not...

use the sysadmin responsibility and see the table details..
Step3:Register the Descriptive Flex field..
Step4:Create a new item and attach the TEXT_ITEM_DESC_FLEX subclass information and set the following properties
Subclass ='Text_Item_Desc_Flex'
Database Items = 'No'
Query Allowed 'Yes'
Insert Allowed 'YES'
Update Allowed 'YES'
List of Values = 'Enable_List_Lamp'
Validate from list 'No'
Form Builder Flexfield a control 1 character size is created on the canvas. Block is correct C01_CHN_REP_BLK
Step5:use a event hanlder to make the code as per oracle standards..
2. Create a Procedure as event handler for the field. This will be used in WHEN-NEW-FORM-INSTANCE
to initialize the flexfield.
PROCEDURE c01_desc_flex( EVENT varchar2) IS
BEGIN
if ( event = 'WHEN-NEW-FORM-INSTANCE') then
FND_DESCR_FLEX.DEFINE( BLOCK=>'C01_CHN_REP_BLK',
FIELD=>'DESC_FLEX',
APPL_SHORT_NAME=>'CUSTOM',
DESC_FLEX_NAME=>'C01_CHN_Descr_flex') ;
else
null ;
end if ;
END;
3. Call the procedure c01_desc_flex , in WHEN-NEW-FORM-INSTANCE
C01_DESC_FLEX(‘WHEN-NEW-FORM-INSTANCE’);
4. Oracle apps provide api FND_FLEX for Descr flex field events. You call it from all events that can edit the DESC_FLEX field.
It is better to write all these block level triggers to have consistent normal behaviour of the descriptive flex field.
FND_FLEX.event('WHEN-NEW-ITEM-INSTANCE') ;
from the WHEN-VALIDATE-ITEM trigger of the DESC_FLEX item as
FND_FLEX.EVENT('WHEN-VALIDATE-ITEM ');
FND_FLEX.EVENT(’PRE-QUERY’);
FND_FLEX.EVENT(’POST-QUERY’);
FND_FLEX.EVENT('WHEN-VALIDATE-RECORD');
FND_FLEX.EVENT('WHEN-NEW-ITEM-INSTANCE');
FND_FLEX.EVENT('PRE-INSERT');
FND_FLEX.EVENT('WHEN-VALIDATE-ITEM');
FND_FLEX.EVENT('PRE-UPDATE);
