User has raised credit memo by mistake with ref. to wrong PO.
How to correct this as there is no any reversal process for it
when u pass credit memo it creates document and which can be seen in PO history tab
Go to <b>Po history</b> pick document number from there and then try to use MR8M
u will be able to cancell credit memo only thing is that u need to cancell fi entry manually
I hope this will solve ur prob
