ABAP AT USER-COMMAND Statement syntax, information and example SAP source code

AT USER-COMMAND

Short Reference

ABAP Syntax AT USER-COMMAND.

What does it do? 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.

Latest notes: 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 trigger 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 trigger 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 trigger the event AT USER-COMMAND , but are handled by the list processor.

Example ABAP Coding 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.
REPORT demo_at_user_command.

START-OF-SELECTION.
SET PF-STATUS 'MYLIST'.
WRITE 'List line'.

AT USER-COMMAND.
IF sy-lsind = 20.
SET PF-STATUS 'MYLIST' EXCLUDING 'MY_SELECTION'.
ENDIF.
CASE sy-ucomm.
WHEN 'MY_SELECTION'.
WRITE: / 'You worked on list', sy-listi,
/ 'You are on list', sy-lsind.
...
ENDCASE.
