Selection screen validation for batch

[Former Member]

This is my scenario:

If program is executed in background, plant (in selection screen) is not mandatory.

If program is executed directly, plant (in selection screen) needs to be filled (mandatory).

I tried using sy-batch and coding at the AT SELECTION-SCREEN portion for validation but it seems that sy-batch is only populated after START-OF-SELECTION.

How do i code it so that if user does not execute program in background, it will prompt an error message and prompt user to fill the plant field in the selection screen?

HI,

use sy-batch in start-of-selection. not in at selection-screen.

start-of-selection.

if sy-batch = ' X' . (If it runs in background)

Then raise message.

endif.

This will work.

Yes i can code in START-OF-SELECTION however, how do i return to selection screen so that user can enter the plant after error message is prompt?
