Differences between PO/SES and Invoice/IR
I have the following problem and I need help, if it ever been faced by someone.
My client have one PO for one service. The service include some materials and the total value for the PO is an amount that include 10 pieces of material. The SES was performed on the total of the PO and, of course, the included materials. Then the Invoice from vendor came for a partial delivery of the activity, including only 2 pieces of material. According to this, the IR was performed only for partial amount. Now, the Credit Memo could been performed only for the SES/quantity for which the IR was performed. From here, now, the cancellation of the SES become stange. It could be canceled only the Invoice quantity/value... And not the original SES quantity/value.
Please, can you help me and tell me if it is possible to cancel the initial quantity/value from SES and how to do it?
Thank you very much. I would appreciate very much a hand of help.
