How can we make DFF mandatory for only few ship to sites while creating receipt

Hello All,

We have DFF in RCV_SHIPMENT_HEADERS

Application:Purchasing

Title:RCV_SHIPMENT_HEADERS

Whenever we create receipt, we will be entering the data on header
DFF. We have three inventory organizations. Each inventory organization is
having multiple ship to locations associated with organization location. We
want to make the DFF mandatory only few ship to location while creating receipt
whereas remaining ship to locations should be non-mandatory

For example.

Inventory organization 1 is having 1 ship to location

INV 1.1(Mandatory)

Inventory organization 2 is having 3 ship to location

INV 2.1(Mandatory), INV 2.2(Mandatory), INV 2.3(Non
mandatory)

Inventory organization 3 is having 2 ship to location
