AT USER-COMMAND

Short Reference

Other versions: 7.31 | 7.40 | 7.54

Syntax


AT USER-COMMAND.

Effect

This statement defines an event block whose event is triggered by the ABAP runtime 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. 
    ... 
  ENDCASE.
