I've got the following issue:
The user have posted an invoice with invoice reduction. The invoice has six items. The invoice item with correction Id "Vendor error: reduce invoice" has associate a blanket PO item with account assignment category U (Unknow). When the user posted the invoice, he or she didn't specify any account assignment object (G/L Account). The user couldn't specify the account assignmet object because the checkbox "Acct.Assignment Chgable at IR" was unchecked in the Account Assignment Category "U".
Then, when the user try to cancel (reverse) the invoice using the transaction MR8M, he or she obtain the error message "ME083: Enter G/L Account".
I've debuged the transaction code and the error message is generated in the FUNCTION mex_lesen_sachkonto.
Do you help me with this issue?
Thanks in advanced.
