Does anyone know of a way to make the Accounting Indicator required at the line item level for Goods Movements in transaction IW42. I have contacted SAP support and have been told the SAP Standard System (ECC6.0) does not accommodate this need. I am currently looking for a user exit where I can develop a solution to this requirement.
I have been reviewing IWO10024 and MB_CF001 but have not been able to conclude if I can safely trigger an error message and return the user to the entry screen and which customer exit is the correct place to accomplish this.
I would like to trigger the message at each "Enter" event and not during the "Save" event if possible. Can this be done or will it cause inconsistencies in the data? Please advise.
