Hello Finance experts
I am not a finance expert but I am having to solve a finance problem , so please bare with me. I am trying to create an Invoice/ credit memo on an existing PO through a BAPI ( interface ) . When i process the data I get a message " Invoice quantity exceeds PO quantity" . To me it looks like a customer validation set on Invoices as the message has a Z001 class. I would like to know where I can see this validation so that I can figure out what it is actually checking. In my case actually the Invoice quantity doesn't exceed PO quantity but it still throws this error.
It would be great if someone can tell me a bit about these validations and messages , where can i find them and set them.
Looking forward to your replies.
