I am changing the quantity (increasing more) from the original PO one, and I am receiving a validation message as an Error and it was supposed to be a Warning message. I have already marked the negative stock for the area-center-deposit in SPRO. Another important fact is that it is not a coded material in Master of Materials. We will appreciate if someone know an OSS NOTE or any kind of help (ECC 6.0).
Thank you in advance.
