HI All,

Now, if user doesnt enters the value of posnr then it should be created automatically.
I have written the code for that ,but this perticlar cell (for which posnr is generated automatically ) should be disabled now.
Can anybody tell me how can i do it?

Hello Sanjay,
  Write a module inside the loop...endloop in the PBO of your screen. Inside the module, check the field and disable it by modifying the SCREEN table.
loop at itab with control tctrl.
  module modify screen.
endloop.
module modify_screen output.
  loop at screen.
   if screen-name cs 'POSNR'.
   if itab-posnr is not initial.
     screen-input = 0.
   else.
     screen-input = 1.
   endif.
   modify screen.
   endif.
  endloop.
endmodule.

Manoj
