Implementing DFF in Custom Form

Implementing DFF in Form consist of two steps Process. The first steps consist of designing the table structure and registration and step 2 consist of enabling in the form.
Steps 1:

• Define DFF fields in the custom tables

ATTRIBUTE1…ATTRIBUTE15 and ATTRIBUTE_CATEGORY are the normal fields used for DFF

• Register the table with Oracle AOL
• Register the DFF with Oracle AOL

For this you have to login into application with :
Application Developer -> Flex Field -> Descriptive -> Register
Then you should specify the name of the DFF (Say BTL_AR_DFF) and specify the associated table.

Step 2:

• Create DFF fields in the custom form

1. Create a form based on the custom table

• Copy TEMPLATE form has example descriptive flexfield which we can use
• Use the TEXT_ITEM_DESC_FLEX property class
• Attach ENABLE_LIST_LAMP_LOV for the field

2. Create a non-base table text item in the block with property class TEXT_ITEM_DESC_FLEX
3. Make sure that DFF is mapped to fields (ATTRIBUTE) of the table and is enabled.

• Next is to call Flexfield Routines to add DFF built-ins in the form to invoke DFF.
  • This consist of these steps:

1. Write, a form level trigger WHEN-NEW-FORM-INSTANCE to invoke the DFF as

FND_DESCR_FLEX.DEFINE(
Block => 'Name of the DFF block',
Field => 'BTL_DFF',
Appl_short_name => 'AR',
Desc_flex_name => 'BTL_AR_DFF',
Title => 'BPL AR More Info' );

2. Write, block level triggers PRE-QUERY and POST-QUERY as

• FND_FLEX.EVENT('PRE-QUERY');
• FND_FLEX.EVENT('POST-QUERY');
• FND_FLEX.EVENT('Pre-Query');
• FND_FLEX.EVENT('When-Validate-Record');
• FND_FLEX.EVENT('Post-Query');
• FND_FLEX.EVENT('When-New-Item-Instance');
• FND_FLEX.EVENT('Pre-Insert');
• FND_FLEX.EVENT('When-Validate-Item');
• FND_FLEX.EVENT('Pre-Update ');
