Stored procedure user exits for table and row level operations
A stored procedure is a program (or procedure) which is physically stored within a database. The advantage of a stored procedure is that when it is run, in response to a user request, it is run directly by the database engine, which usually runs on a separate database server and is generally faster at processing database requests.
After writing and compiling user exit programs, you can specify at which user exit point you want to invoke the user exit (either before or after a row-level or before or after a table-level operation) on the User Exits tab of Management Console.
