Hi..,

Ya u can solve this by using AT EXIT-COMMAND..

When u are defining the Status in Menu painter .. For BACK or EXIT or CANCEL u need to give the function type as 'E' ( by default it is space ).

Now in the AT EXIT_COMMAND event write...

In the Dynpro in PAI event .. u need to call the module as MODULE CANCEL AT EXIT-COMMAND.

in THE Module pool program ...

MODULE CANCEL.

case sy-ucomm.

when 'BACK' OR 'CANCEL'.

leave program.

endcase.

ENDMODULE.

reward if it helps u...

To solve this, you can either use AT EXIT COMMAND or declare the selection screen field without making it obligatory and in the code you can check if the field is not initial before processing it.

standard transactions also works in the similay way, If you dont want that remove the mandatory option and use this

in PAI

loop at screen.
  if screen-name = 'FIELD_NAME'.
     screen-required = '1'.
     modify screen.
  endif.
endloop.

Prasanth,

For mandatory , Double click on that field goto attribute select the check box input required.

Type E Function Codes

You can assign the function type E to the function codes of both pushbuttons on the screen and of elements in the GUI status. To do this for a pushbutton, set the Function type attribute in the Screen Painter to E. To do it in the GUI status, choose Goto ® Object lists ® Function list in the Menu Painter, select the required function codes, and enter E for the function type.

PROCESS AFTER INPUT.

MODULE CANCEL AT EXIT-COMMAND.

MODULE BACK AT EXIT-COMMAND.

MODULE CANCEL INPUT.

MESSAGE I888(BCTRAIN) WITH TEXT-001 OK_CODE INPUT1 INPUT2.

IF OK_CODE = 'CANCEL'.

CLEAR OK_CODE.

LEAVE PROGRAM.

ENDIF.

ENDMODULE.

MODULE BACK INPUT.

MESSAGE I888(BCTRAIN) WITH TEXT-002 OK_CODE INPUT1 INPUT2.

IF OK_CODE = 'BACK'.

CLEAR: OK_CODE .

LEAVE TO SCREEN 100.

ENDIF.

ENDMODULE.

Don't forget to reward if useful...
