CO-PC message error CKMLLA 202

Dear all, we are facing an issue on the Process Order reverse due a Material Ledger.

Message error: CKMLLA - Cross-period reversal not possible on account of active material Ledger.

scenario: We had a process order manual appointment on FEB-2014 but this one was did wrong and now we need to revert it, but when trying to reverse the process order on MAR-2014 the message CKMLLA is appear, i think it´s happen because the Material Ledger for FEB-2014 already performed.

Do you have any way to reverse it for MAR-2014 or is it necessary to revert it for APR-2014?

Thanks for support.
