screen to selection screen flow issue

[Former Member]

I have a selection screen 1000 which contains fields, execute button and a custom buttom FC01. When I click on the button FC01, it takes me to another screen 200. When I go back to selection screen from screen using BACK button, I am not able to hit the execute button to run report.

This is what I am doing for flow of screen 200.

case save_ok.
when 'BACK': call selection-screen 1000. leave to screen 1000.

I have also tried 
when 'BACK': set screen 1000. leave screen.

Both do nothing the first time I press execute button, the second time I press it they give out errors. It seems after I press the BACK button from the screen 200 to move into selection screen 1000. The flow is still in screen 200 as when I check sy-dynnr .. its still equals 200. I need to be able to go back to the selection screen 1000 from screen 200 and still retain the input that was entered by user. Please advise

Hello Megan,

This works for me, please try this code:

It retains the values from the second selection screen 200.

In the second screen, you need to press the run button to go back to the main selection screen.

REPORT  ZTEST_NP.

TABLES SSCRFIELDS.

DATA functxt TYPE smp_dyntxt.

PARAMETERS: P_NUM1 TYPE I.
SELECTION-SCREEN FUNCTION KEY 5.

SELECTION-SCREEN: BEGIN OF SCREEN 200.
PARAMETERS: P_NUM2 TYPE I.
SELECTION-SCREEN: END   OF SCREEN 200.


INITIALIZATION.
  functxt-quickinfo = 'Screen 200'.
  functxt-icon_text = 'Screnn 200'.
  sscrfields-functxt_05 = functxt.

AT SELECTION-SCREEN.
  CASE SSCRFIELDS-ucomm.
    WHEN 'FC05'.
      CALL selection-SCREEN 200 starting at 10 10.
  ENDCASE.

START-OF-SELECTION.
  WRITE: / 'num1', P_NUM1,
         / 'num2', P_NUM2.
