Hi SAP Gurus,
I need help for reference field, I have made the reference field as a mandatory field through T-Code OBA7.
Now I want that the information / data which I will enter in the reference field should be unique which means if will enter the same information again in the next transaction in FB60 system will immediately throw an error & will not accept the same information which I have enter in the earlier transaction.
Eg. In the first transaction I have enter 125 in reference field in FB60 transaction then in the 02nd transaction if will again try to enter 125 then the system should immediately throw an error & it should not accept the same value.
Kindly guide me the procedure how to do this to activate this feature.
Waiting for the response.
Regards,
Amitabh
