Functions of routines at user exits

You can use exit routines to accomplish a variety of tasks:

Figure 1, Table 1, and Table 2 summarize the functions of user exit routines and the exits and phases with which they can be associated.

The following restrictions apply to the applications for which specific user exits can be used:

E11. E16, E17, E18 and E19 can be used for sort applications, but are ignored for copy or merge applications.
E15 can be used for sort or copy applications, but is ignored for merge applications.
E32 can be used for merge applications, but is ignored for copy or sort applications.
E61 can be used for sort or merge applications, but is ignored for copy applications.
E31, E35, E37, E38 and E39 can be used for sort, copy or merge applications.
