Hi MoazzaM,
Although, it was not cause of the Variant field ( which was blank) but the Incompletion procedure in the section Transaction Flow for the Doc type ZKR, it was set to Credit memo. I have changed it to Sales Order, and all the fields which were blank and un-editable are now populated in the newly created Returns order but not in the one where i saw the issue. This is just FYI..
Anyway, thanks for indicating towards the right direction. Its working fine now.
