This statement defines an event block whose event is triggered by the ABAP runtime environment if, when a screen is displayed, a function with a self-defined function code is chosen. The function code is available in the system field sy-ucomm when processing starts.

Self-defined function codes are all those that include character combinations, except for the following:

  • The function codes "PICK" and "PFnn" ("nn" stands for 01 to 24) do not raise the event AT USER-COMMAND, but the events AT LINE-SELECTION and AT PFnn instead.
  • All function codes that start with the character "%" are interpreted as system functions and do not raise the event AT USER-COMMAND. The system functions for lists are listed in the following table 1.
  • The function codes in the following table 2, likewise, do not raise the event AT USER-COMMAND, but are handled by the list processor.

This program works with a self-defined GUI status MYLIST. The function associated there with the function code MY_SELECTION triggers the event AT USER-COMMAND when the list is displayed and also creates details lists.
