How to restrict duplicate data in DFF by using form personalization.

  Hi,

 

We are using DFF for Capturing Vendor Excise invoice number at the time of PO receipt i.e In this DFF user put the excise invoice number for particular supplier Receipts.

 

Problem is user make two receipts for one excise invoice number by mistake and system not restrict it

But restrict it at the time of cenvat claim ( India localization FORM).

 

Now I want to restrict user at the time of PO Receipt creation by using form personalization (to avoid any delicacy in DFF)
