In our process we create service entry sheets for service process. In SAP once if service entry sheet is created and the p.o qty is exhausted, system still allows me to create dummy document (service entry sheet) which are available as error documents in the system against the p.o - these are accidently created by the users.
Is there any provision to prevent users from creating the SES once the p.o qty is fully exhausted. - i.e., system should throw error message and prevent user from creating the SES.
Can I know why this is kept as standard functionality in SAP - What is the use of the parked document which is not processable at any point of time?
