Exception reports within SAP
I am looking for any information on built-in exception reports within SAP, do these exist? The company I work for typically runs custom reports to identify duplicate payments, receiving errors, missed opportunities based on payment terms, etc. These reports are generated outside SAP. I have been able to use screen MB5S (GR/IR Balances) to isolate over received purchase orders, but I am interested to learn more about the tools that are built into SAP. Any help is appreciated!
