Need help to correct credit memo price for returns PO
I need some advice on how I can correct the credit memo price for return PO. This return PO is created without reference to the original PO. 161 movement and credit memo posted. User just realised that the return PO price is too high.
As shipment was done long time back, and it's a serialised part. It is not possible to reverse the credit memo and the shipment. how can the credit memo price be reduced? can subsequent debit be posted?
Kindly provide some guidance
