HI ,

u can use the following code.

at selection screen output .

if material_no is not initial and invoice no is not initial.

loop at screen .

if screen-name = 'Batch no'.

screen-input = 0.

screen-output = 1.

modify screen.

endloop.

endif.

same logic for other one.

hi,

Use AT SELECTION-SCREEN ON <FIELD> event.

Write this Event for all the three fields.

Place the Blocking code in the Event based on the condition.

Hii,

Try this logic

REPORT z_sdn.


PARAMETERS:
  p_matnr     TYPE mara-matnr MODIF ID abc,
  p_invc(10)  TYPE c MODIF ID abc,
  p_batch(10) TYPE c MODIF ID xyz.


AT SELECTION-SCREEN OUTPUT.

  IF p_matnr IS NOT INITIAL OR p_invc IS NOT INITIAL.
    LOOP AT SCREEN.
      IF screen-group1 EQ 'XYZ'.
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ELSEIF p_batch IS NOT INITIAL.
    LOOP AT SCREEN.
      IF screen-group1 EQ 'ABC'.
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ENDIF.


START-OF-SELECTION.


  WRITE: 'TEST'.

Hi Srinivas,

You get this functionality using AT SELECTION-SCREEN OUTPUT Event.

If not  p_matno is initial or p_invoiceno is initial.
  loop at screen.
    if screen-name = p_batchno.
      screen-input = 0'.
      modify screen.
    endif.
  endloop. 
endif.

Best regards,

Hi,

You can use loop at screen concept here.

IF Material No = 'X' or

Invoice No = 'X'.

LOOP AT SCREEN.

IF screen-group1 = 'SG2'.

screen-active = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENIDF.

For the second condition also same thing u have to do.

Kusuma.

Hi,

Check the following code:

PARAMETERS:

p_matnr TYPE mara-matnr MODIF ID abc,

p_invc(10) TYPE c MODIF ID klm,

p_batch(10) TYPE c MODIF ID xyz.

AT SELECTION-SCREEN OUTPUT.

IF p_matnr IS NOT INITIAL.

IF p_invc IS NOT INITIAL.

LOOP AT SCREEN.

IF screen-group1 EQ 'XYZ'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ELSEIF p_batch IS NOT INITIAL.

LOOP AT SCREEN.

IF screen-group1 EQ 'KLM'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.

ENDIF.
