PO Header DFF Update

Hi All,

we have create a PO Header DFF  ( Attribute7) and Updated DFF Value to " Y" ( Around 900 PO's, from backend) and for some  POs we found that DFF value has not updated to "Y".

Not Sure what makes to causing this issue. we found that this issue is happened for the order who's "ATTRIBUTE_CATEGORY" is null in backend. not sure why this is not updated.

DFF Created as shown below.

After Update from back end.

From Core forms. DFF Value still shows as "N".

List of Orders for which Backend shows as DFF updated with Y but application forms shows as "N".
