Is Clarification GL required for Return lot posting FP09 ?

Hi Experts,

I would like to know how to handle following scenario

When we post returns using Return lot  FP09 transaction -  But i am trying to post without Clarification GL account  but system is throwing error saying Clarificaion account is required.

But the problem is Business is not in a position to give Clarification GLs for this return postings, is there any way to post without Clarification GL?

If will i try to post with Clarification GL what entries i have to pass for Return lot ,(now i am using Internal interim G Ls not using Main Bank GLs for Payments}

Any suggestions/inputs are greatly appreciated.

Thanks,

ABC
