SET USER-COMMAND

Short Reference
• SET USER-COMMAND ABAP Statement


ABAP Syntax SET USER-COMMAND fcode.

What does it do? Triggers a list event with a function code specified in fcode. fcode must be a character-type data object. You can use this statement when generating a list. After completion, but before display of the current list, the runtime environment responds as if a user action were performed in the displayed list using the function code specified in fcode.

The assignment of list events to function codes corresponds to the description under AT USER-COMMAND: The predefined function codes of the tables listed under AT USER-COMMAND are caught by the runtime environment The function codes 'PICK' and 'PFnn' trigger the events AT LINE-SELECTION or AT PFnn all other functions trigger the event AT USER-COMMAND

If the corresponding event block is implemented, the value of sy-lsind is increased by one and the event block is executed.

If you use multiple SET USER-COMMAND statements while creating a list, the system executes only the last one.

Latest notes:The function code 'PICK' only triggers an event if the cursor is positioned on a list row. If a function code is assigned to the 'Return key in the current GUI status, this function code is used instead of the one specified in fcode.
