Hi there. If you want to grey out a parameter in your selection screen so that the user cannot change or enter data, here's what you need to do. First use a modif ID with the field. Then before your start of selection you will change the screen input value. Here is some sample code:

PARAMETERS: p_field LIKE rlgrap-filename MODIF ID fpn.

AT SELECTION-SCREEN OUTPUT.

• make any parameter in group FPN display only

• (gray out areas we don't want user to change)

LOOP AT SCREEN.

CHECK screen-group1 = 'FPN'.

screen-input = 0. "Output (Display) only

MODIFY SCREEN.

ENDLOOP.

I hope this helps.

hi,

In ABAP, we will not have any events like lost_cursor similar to VB.

At selection-screen gets triggered once we press Enter after giving input to First parameter. So, that validation can be done for first parameter and make the second parameter grayedout.

Okay. Then try this (assuming that you have MODIF ID fpn assigned to p_field2):

AT SELECTION-SCREEN.

IF p_field1 > space. "change this to whatever you need to check for field1 to be valid

LOOP AT SCREEN.

CHECK screen-group1 = 'FPN'.

screen-input = 0. "Output (Display) only

MODIFY SCREEN.

ENDLOOP.

ENDIF.

Hi Hraichi,

PARAMETERS: P_MARA TYPE MARA-MATNR.

PARAMETERS: P_MATKL TYPE MARA-MATKL.

AT SELECTION-SCREEN.

LOOP AT SCREEN.

IF SCREEN-NAME = 'P_MARA' AND P_MATKL IS NOT INTIAL.

SCREEN-INPUT = '0'.

MODIFY SCREEN.

ENDIF.

IF SCREEN-NAME = 'P_MATKL' AND P_MARA IS NOT INTIAL.

SCREEN-INPUT = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

Thanks,

Hi,

You can disable the parameter by setting SCREEN-INPUT as 0 to grayed out in the AT SELECTION-SCREEN event.

PARAMETERS: P_MARA TYPE MARA-MATNR.

AT SELECTION-SCREEN.

LOOP AT SCREEN.

IF SCREEN-NAME = 'P_MARA'.

SCREEN-INPUT = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

Thanks,

How about using radio-buttons to select the active field. Something lie this:

  SELECTION-SCREEN BEGIN OF LINE .
  PARAMETERS : r_p1 RADIOBUTTON GROUP fred DEFAULT 'X' USER-COMMAND bob ,
               p_p1 TYPE char20 MODIF ID pa1 .
  SELECTION-SCREEN END OF LINE .
  SELECTION-SCREEN BEGIN OF LINE .
  PARAMETERS : r_p2 RADIOBUTTON GROUP fred ,
               p_p2 TYPE char20 MODIF ID pa2 .
  SELECTION-SCREEN END OF LINE .

  AT SELECTION-SCREEN OUTPUT .
    LOOP AT SCREEN .
      IF screen-name EQ 'P_P1' .
        IF r_p1 EQ 'X' .
          MOVE '1' TO screen-input .
        ELSE .
          MOVE '0' TO screen-input .
        ENDIF .
        MODIFY SCREEN .
      ENDIF .
      IF screen-name EQ 'P_P2' .
        IF r_p2 EQ 'X' .
          MOVE '1' TO screen-input .
        ELSE .
          MOVE '0' TO screen-input .
        ENDIF .
        MODIFY SCREEN .
      ENDIF .
    ENDLOOP .

Have a good weekend!
