Cancel of SD rebate settlement

Hello

My problem is, that the rebate accruals in SD has not been updated for invoices issued in past years.

After update/final settlement of an rebate agreement in SD valid from 2009-2011, I now get provision postings in 2012 related to the invoices issued in 2009-2011. Unfortunately I am not able to reverse the postings (VF11 or FB08) - this will also reverse the original invoice, which I do not want to. I only want to reverse the bonus accrual in 2012.

Hope somebody can help me!

BR
