FMJ3 - Reverse Carryforward

Dear experts,

When executing transaction FMJ3 to reverse commitment carryforwards made from 2014 to 2015 I get the error message “FMCF110 - The document item was reassigned after the commitment carryforward”. I have several documents in the situation, I understand that this documents already suffered changes in the new year and thus have a new account assignment. The problem is that I need to reverse them to the previous year anyway.

Is there a way to reverse or reset the new account assignment so that it goes back to the previous one? In this way I could reverse the carryforward.

Thanks in advance.

Best regards,
