Field selection at document level.

Hi,

I want to make the following fields as required fields for the field selection group FOF ( ie only for Frame work purchase order FO )

1. Reason for Rejection ( EKKO - ABSGR )

2. Reason for Ordering ( EKPO - BSGRU )

Even after selecting the fields as required fields it is not getting reflecting while creating the PO.

Buf if I set it as the Field selection group ME21N, it is working . I dont want to have this field as mandatory for all of the Purchase orders.

PL suggest how to go about.

Regards,

R. Dillibabu.
