ID DYNPRO% • AT USER-COMMAND ABAP Statement
AT USER-COMMAND Short Reference
ABAP_SYNTAX AT USER-COMMAND.
What does it do? This statement defines an event block whose event is raised by the ABAP runtime framework if, when a screen list is displayed, a function with a user-defined function code is chosen. The function code is available in the system field sy-ucomm when processing starts. User-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, and instead raise the events AT LINE-SELECTION and AT PFnn.
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.

Example ABAP Coding
The following section of an executable program works with a user-defined GUI status MYLIST. The function linked there with the function code MY_SELECTION raises the event AT USER-COMMAND when the list is displayed and creates details lists. ABEXA 00048 ABAP_EXAMPLE_END
