Dynamic Selection Screen

Former Member — Tue, 04 Jan 2005 06:53:58 GMT

Hello everyone,

In my Report program I have two option buttons and two field parameters. The fields for my field parameter will correspond with the two option button I created. Meaning, when I choose option one, the reference fields for my field parameters will be from table1 else it will be from table2. Is this possible?

Thanks a lot,

Jeff

Hi Jeffrey,

I think this is possible. This is a small code snippet. Try out and let me know, if I am way tangent here.



SELECTION-SCREEN BEGIN OF BLOCK blk.
PARAMETERS : p_rb1 TYPE c RADIOBUTTON GROUP rad1 DEFAULT 'X' USER-COMMAND FC,
             p_rb2 TYPE c RADIOBUTTON GROUP rad1.
SELECTION-SCREEN END OF BLOCK blk.

SELECTION-SCREEN BEGIN OF BLOCK blk_1 WITH FRAME.
PARAMETERS : p_werks1 TYPE werks_d MODIF ID bk1.
SELECTION-SCREEN END OF BLOCK blk_1.

SELECTION-SCREEN BEGIN OF BLOCK blk_2 WITH FRAME.
PARAMETERS : p_werks2 TYPE werks_d MODIF ID bk2,
             p_matnr2 TYPE matnr   MODIF ID bk2.
SELECTION-SCREEN END OF BLOCK blk_2.


AT SELECTION-SCREEN OUTPUT.
  IF p_rb1 = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'BK1'.
        screen-active = 0.
        MODIFY SCREEN.
      ELSE.
        screen-active = 1.
        MODIFY SCREEN.
      ENDIF.

    ENDLOOP.
  ELSE.
    LOOP AT SCREEN.
      IF screen-group1 = 'BK2'.
        screen-active = 0.
        MODIFY SCREEN.
      ELSE.
        screen-active = 1.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ENDIF.

Let me re-phrase my answer.

You cannot change the reference of a parameter at runtime.

But you can have two set of parameters with different references and hide/unhide them based on the option selected.
