AT USER-COMMAND

Short Reference

Syntax

AT USER-COMMAND.

Effect

This statement defines an event block whose event is triggered by theABAPruntime environment if, during the display of a screen list, a function with a self-defined function code was chosen.

Note

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 cause the event AT USER-COMMAND, but the events AT LINE-SELECTION and AT PFnn.
  
• All function codes that start with the character "%" are interpreted as system functions and do not cause 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 cause the event AT USER-COMMAND, but are handled by the list processor.

Example

This program works with a self-defined GUI status MYLIST. The function that is linked there with the function code MY_SELECTION causes the event AT USER-COMMAND during list display 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.
