FlexFields Interview Q & A:

FLEX FIELD:

What is the difference between key flexfield and Descriptive flexfield?
Key Flexfield is used to describe unique identifiers that will have a better meaning than using number IDs. e.g a part number, a cost centre etc
Desc Flex is used to just capture extra information.
Key Flexfields have qualifiers whereas Desc Flexfields do not.
Desc Flexfields can have context sensitive segments while Key flexfields cannot.
And one more differenct that KFF displays like text item but DFF displays like [ ] .

Which procedure should be called to enable a DFF in a form?
FND_DESCR_FLEX.DEFINE
(BLOCK                                 => 'BLOCK_NAME'
                ,FIELD                                    => 'FORM_FIELD_NAME'
               ,APPL_SHORT_NAME      => 'APP_NAME'
               ,DESC_FLEX_NAME         => 'DFF_NAME'
               );

In Brief,
We need to follow the following steps in your form:
a) Create a displayed field to hold your concatenated segment values (the [ ] field).
b) Create fields (normally hidden) for each of the flexfield columns in your table (the
      one used for your flex).
c) In the form-level WHEN-NEW-FORM-INSTANCE,
call FND_DESCR_FLEX.DEFINE,
setting BLOCK parameter to the name of the block containing your [ ] field,
the FIELD parameter to the name of your [ ] field,
the APPL_SHORT_NAME parameter to the short name of your application and the DESC_FLEX_NAME parameter to the name of your descriptive flex.

In the form-level WHEN-NEW-ITEM-INSTANCE,
WHEN-VALIDATE-ITEM,
PRE-INSERT,
PRE-UPDATE,
POST-QUERY and
PRE-QUERY triggers place a call to FND_FLEX.EVENT as follows:
         FND_FLEX.EVENT ( 'TRIGGER_NAME');
where TRIGGER_NAME is the name of the trigger,
e.g. in the PRE-QUERY trigger .... FND_FLEX.EVENT('PRE-QUERY');
Which procedure should be used to make the DFF read only at run time?
FND_DESCR_FLEX.UPDATE_DEFINITION()

What is the difference between flexfield qualifier and segment qualifier?
