Program At Exit Command


Scenario : Generally if a screen contains any obligatory(Required) input field & we execute the MP program , the screen appears & if we want to come out of the program it will not allow us . We have to fill the mandatory field on the screen and then we can come out of the program by clicking on the application tool bar buttons. To overcome this problem , generally we use AT EXIT-COMMAND at PAI of the screen to force exit from the screen that contains a required field without filling any value to it.

Here we have two screens 9000 and 9001. In the 9000 screen we have an required i/p field & a single record is displayed on 9001 screen based on the i/p.



data : p_carr type spfli-carrid,
wa_spfli type spfli,
ok_code type sy-ucomm.

module STATUS_9000 output.
SET PF-STATUS ‘STATUS’. ” DOUBLE CLICK ON ‘STATUS’ TO CREATE IT
