User exits or BTEs for vendor invoices
Can any body tell me the common user exit or the BTE which will applicable for the transaction codes
'FB01', 'F-90', 'FB01','FB60','FB65','FV60','FV65'.
I need only the common user exits across the above transaction codes.Because i know the user exits individuvally for each transactions. But i need to some validations which will be common across all the above transactions.
