Usually if the screen contains any required or mandatory input field & we run the Module pool program, the screen appears & if we want to come out of the program it will not allow us. We have to give the mandatory field on the screen & then we can come out of the program by clicking on the application tool bar buttons. To overrule this issue, generally we use AT EXIT-COMMAND at PAI of the screen to force come out from the screen that contains a required field without filling any value to it.
Lets take an example that we have two screens 9000 & 9001. In the 9000 screen we have required input field and a single record is displayed on 9001 screen based on the input.
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 * SET TITLEBAR ‘xxx’. endmodule. ” STATUS_9000 OUTPUT module FORCE_EXIT input. CASE OK_CODE. WHEN ‘EXIT’ OR ‘CANCEL’. LEAVE PROGRAM. ENDCASE. endmodule. ” FORCE_EXIT INPUT module USER_COMMAND_9000 input. case ok_code. WHEN ‘DISP’. CALL SCREEN 9001. WHEN ‘BACK’. LEAVE PROGRAM. endcase. endmodule. ” USER_COMMAND_9000 INPUT module STATUS_9001 output. * SET PF-STATUS ‘xxxxxxxx’. * SET TITLEBAR ‘xxx’. SELECT SINGLE * FROM SPFLI INTO WA_SPFLI WHERE CARRID = P_CARR. endmodule. ” STATUS_9001 OUTPUT module USER_COMMAND_9001 input. case ok_code. when ‘BACK’. LEAVE TO SCREEN 0. endcase. endmodule. ” USER_COMMAND_9001 INPUT

FLOW LOGIC OF SCREEN 9000 PROCESS BEFORE OUTPUT. MODULE status_9000. PROCESS AFTER INPUT. MODULE force_exit AT EXIT-COMMAND. MODULE user_command_9000.
FLOW LOGIC OF SCREEN 9001 PROCESS BEFORE OUTPUT. MODULE STATUS_9001. PROCESS AFTER INPUT. MODULE USER_COMMAND_9001.
