accrual reversal for archived invoices in CCM / settlement management

Hi,

there are several old contract which have still posted accruals, but the invoices which belongs to the business volume were archived in the meantime. I tried to settle the contracts as well as to release the accruals with WB2R_RAC but I get always the same error message: "Internal error: Not all accruals could be distributed"

I guess that the distribution failed due to the archived invoices. Has anybody an idea how to release the accruals?
