Selection Screen Processing..

[Former Member]

Haii All..

I have done a program in which i have a selection-screen and a respective alv list, but the problem is that when i click f3 button on the alv list screen i should come back to the selection-screen and the previous input values shouldnt be gone so that i could continue with selection..

I have used leave to transaction sy-tcode, but the problem is that when i click the f3 button on the output screen, i come back to the selection-screen but the transaction is startting newly..and i am losing the previous values given in the selection-screen and when i use call selection-screen 1000 i am not able to come out of the selection-screen when i click f3 on the selection-screen.

Assign the function code you want to the back button in PF-status.

There is no need of calling the screen again. The values will not be lost when you do like this

See this code:

case sy-ucomm.

when 'BACK'.

call selection-screen 1000.

• leave to transaction sy-tcode.

when 'CANCEL'.

leave program.

endcase.

when i click f3 it should come back again to the selection-screen, which is successfull for me and also the values are not lost..but the problem is that when i cilck f3 on the selection-screen m going to the output screen again rather than quit the program.

so i used leave to transaction sy-tcode, here m getting out of program but the values are lost in the selection-screen.

Hope its clear for u now.

Try this.

case sy-ucomm.
when 'BACK'.
  set screen 0.
  leave screen.

when 'CANCEL'.
  leave program.
endcase.

Oh My God..Thanks a lot!

Its working now..

[RichHeilman]

Yep, what is happening here is that you are now saying that there is no "Next screen" in the sequence, and you are leaving the current screen, which will always end the current screen and show the previous.

Ok..thanks a lot for the answer..so is it that when we leave the current screen (for example output screen) and go back to the previous screen (input screen) the screen number is automatically assigned to the current screen.
