SET

Basic form

SET USER-COMMAND f.

Effect

Only valid with report list output:

Sets the contents of the field f as USER-COMMAND and executes them immediately when the list is next displayed (i.e. the system suppresses the list display und immediately processes the event AT LINE-SELECTION , AT USER-COMMAND or, in the case of a system function code (list of reserved function codes, see AT USER-COMMAND ), this system function).
The effect is exactly as if the user had entered the function in the command field and pressed ENTER . This means that the current positioning of the list (SCROLL ) and the cursor (SET CURSOR ) is taken into account.

Note

You can specify SET USER-COMMAND several times in the same event.
If you set several functions one after the other with USER-COMMAND when creating a list, only the last one is effective.
If the function key ENTER in the GUI status of the relevant list itself contains a function code, this is executed rather than that specified with SET USER-COMMAND .

Example

Process a line selection immediately:


WRITE: 'List'...  "Create a list
SET CURSOR LINE 7.


SET USER-COMMAND 'PICK'.

The event AT LINE-SELECTION is processed immediately for list line 7.

Example

Process a function immediately:


WRITE: 'List'...  "Create a list


SET USER-COMMAND 'FUN'.

Processes the event AT USER-COMMAND immediately; the system field SY-UCOMM contains the function code FUN .

Example

Leave list immediately:


WRITE: 'List'...  "Create a list


SET USER-COMMAND 'BACK'.

The list is not displayed, but is left immediately.

Example

Create list with dialog box 'Find by...':


WRITE: 'List'...  "Create a list


SET USER-COMMAND '%SC'.
