Hi Sirisha,
Goto menu painter and give given status for ur program-> go to standard tool bar and double click on BACK and select Function type = E.
or
double click on ur PF status  and do the same.
once you give function type E, write one module under PAI like below.
PROCESS AFTER INPUT.
MODULE BACK AT EXIT-COMMAND.
code for Module BACK
IF ok_code = 'BACK' OR ok_code = 'EXIT'.
    CLEAR: ok_code.
    LEAVE TO SCREEN 100." This is the screen where u want to come back
  ENDIF.
ENDMODULE.
This module BACK is executed wherever u write under PAI when Function type E is defined for Screen Element.
for more details on this topic. please have a look.
