Call screen from PAI of another screen

[dpto_informatica]

I've created my program with two dynpro.

At the beggining shows an screen to view an OO ALV with two buttons, when i've push the second i want to show the second screen just using the CALL SCREEN '1200'.  But i'm still watching the first screen.

DYNPRO 1100:

  PROCESS BEFORE OUTPUT.
    MODULE STATUS_1100.
    MODULE SEL_DATA_1100.
    MODULE SHOW_DATA_1100.

  PROCESS AFTER INPUT.
    MODULE USER_COMMAND_1100.

With this button cod function TOTPRIM:

In the USER_COMMAND_1100 of the PAI:

  CASE sy-ucomm.
      WHEN 'TOTPRIM'.
        CALL SCREEN '1200'.
    ENDCASE.

What i'm doing wrong.

Thanks in advance.

Impossible to say precisely without reproducible code. Many bugs in your program may correspond to this symptom.

The button image doesn't look like an SAP GUI screenshot, and not even a button from OO ALV. As you don't say exactly what is your global code, my two cents: either you are using an ALV Grid with parent CL_GUI_CONTAINER=>SCREEN0 or alike, without freeing it, or you do a SUPPRESS DIALOG or LEAVE SCREEN or alike in the display of screen 1200.

All your code till now is fine, no reason to not display the screen 1200. By the way, you have debugged your program, so you are sure that you are entering the PBO of screen 1200, right?

[Sandra_Rossi]

You are saying now "After the CALL SCREEN '1200' on the PAI it goes to the PBO of the 1100 dynpro and not to the 1200 dynpro PBO" (2), but the initial question was different "when i've push the second i want to show the second screen just using the CALL SCREEN '1200'. But i'm still watching the first screen." (1). What is the actual question, (1) or (2)?

Both are the same. If it goes to the 1100 dynpro PBO it will show the 1100 dynpra, that is the first screen. And i need to go to 1200 pbo dynpro to show the 1200 dynpro

Better focus on just one case otherwise it's difficult to understand. I think that the discussion will be endless, so either ask a fellow programmer in your company (or anyone you can discuss with), or create a test program where you can reproduce the error, and post the whole code here. Thank you.
