Change select-options at runtime

Former Member — Wed, 20 Apr 2011 06:27:16 GMT

Hi all,

I want change the behavior of a select-options field at runtime.

e. g.

At the beginning of the program the intervals are enabled.

After the user pushes a radiobutton the select-options field should be changed to no-intervals.

How can I change the select-options field at runtime?

regards

Hi,

You may try with

AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
     IF screen-group1 = 'MOD'.
*   select-option with intervals.
     ELSE
*   select-option with no intervals.
     ENDIF.
MODIFY SCREEN.
ENDLOOP.

You may check the sample code for the same in the below link.

Run the following Example:


TABLES: vbak, ltak.
DATA:err_sw.
PARAMETERS: rb1 RADIOBUTTON GROUP rb1 USER-COMMAND sel DEFAULT 'X'.
PARAMETERS: rb2 RADIOBUTTON GROUP rb1.

SELECTION-SCREEN: SKIP 1.

SELECTION-SCREEN: BEGIN OF BLOCK b1 WITH FRAME TITLE text-t01.
SELECT-OPTIONS: sauart FOR vbak-auart DEFAULT 'ZRE' NO INTERVALS MODIF ID rb1.
SELECT-OPTIONS: sdate FOR vbak-erdat MODIF ID rb1.
SELECTION-SCREEN: END OF BLOCK b1.

SELECTION-SCREEN: BEGIN OF BLOCK b2 WITH FRAME TITLE text-t02.
SELECT-OPTIONS: stanum FOR ltak-tanum MODIF ID rb2.
SELECT-OPTIONS: sbdatu FOR ltak-bdatu MODIF ID rb2.
SELECTION-SCREEN: END OF BLOCK b2.

AT SELECTION-SCREEN OUTPUT.
IF rb1 = 'X'.
PERFORM hide_rb2_options.
ELSE.
PERFORM hide_rb1_options.
ENDIF.

INITIALIZATION.

START-OF-SELECTION.
CLEAR err_sw.
IF rb1 = 'X'.
IF sauart IS INITIAL
OR sdate IS INITIAL.
MESSAGE i208(00) WITH 'not entered'.
err_sw = 'X'.
ENDIF.
ELSE.
IF stanum IS INITIAL
OR sbdatu IS INITIAL.
MESSAGE i208(00) WITH 'not entered'.
err_sw = 'X'.
ENDIF.
ENDIF.

CHECK err_sw NE 'X'.

WRITE:/ 'Hi!'.

Hello,

You can try this workaround though:

DATA: v_bukrs TYPE bukrs,
      r_bukrs TYPE RANGE OF bukrs.

PARAMETERS: rb1 RADIOBUTTON GROUP g1 USER-COMMAND cmd DEFAULT 'X',
            rb2 RADIOBUTTON GROUP g1.
SELECT-OPTIONS: s_bukrs1 FOR v_bukrs MODIF ID m1,
                s_bukrs2 FOR v_bukrs NO INTERVALS MODIF ID m2.

AT SELECTION-SCREEN OUTPUT.

  IF rb1 = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'M2'.
        screen-output = '0'.
        screen-active = '0'.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ELSE.
    LOOP AT SCREEN.
      IF screen-group1 = 'M1'.
        screen-output = '0'.
        screen-active = '0'.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ENDIF.

  START-OF-SELECTION.

  IF s_bukrs1[] IS NOT INITIAL.
    r_bukrs = s_bukrs1[].
  ELSEIF s_bukrs1[] IS NOT INITIAL.
    r_bukrs = s_bukrs2[].
  ENDIF.

* For further processing use R_BUKRS instead of screen elements!!!

I thought the function SELECT_OPTIONS_RESTRICT should help, but as per the documentation it won't:

The latest you can call it is in the PBO of the first selection screen to be displayed. If you call it any later, the exception TOO_LATE occurs.

Hope this helps.

BR,
