Selection screen

[Former Member]

Hi ,

I have 2 parameters in Selection screen.

If field1 is null then I have to make the field 2 as Mandatory.If Field1 has some value then I have to proceed with the value...no need to make field 2 as mandatory.

Help me on this.

Hi,

Put this code at event : AT SELECTION-SCREEN OUTPUT.

if field1 is initial.
loop at screen.
if screen-name = 'FIELD2'.  
  screen-required = 1.    
  modify screen.  
endif.
endloop.
endif.

or

AT SELECTION-SCREEN .

IF field1 IS INITIAL.
  if field2 is initial.
     MESSAGE e000(xx) 'enter data for field2'.
  ENDIF.
ENDIF.

hi,

To keep both the fields open for input, keep them under the same block.

If we dont keep them under same block, as soon as an error message is thrown, only second field

will be open for input and the first field will be grayed.

selection-screen begin of block b1 with frame title text-001.

parameters : p_first type c,

p_scnd type c.

selection-screen end of block b1.

At selection-screen on block b1.

If p_first is initial.

if p_scnd is initial.

message e000 with 'Enter value in p_scnd'.

endif.

endif.

          S_PLNKN IS INITIAL OR
          S_VORNR IS INITIAL OR

HI,

Try one of the following two methods,

which suit you better.

<b>REPORT ztest.

tables: bkpf.

parameter: a(10) default 'dd' MODIF ID ABC.
select-options: b for bkpf-belnr MODIF ID SEL.


AT selection-screen on  a.

if a is initial.
message e000(su) with 'enter in a'.
endif.</b>

OR

<b>at selection-screen output.
  If  a is initial.
    loop at screen.

      if screen-group1 = 'SEL'.
        screen-required = 1.
        modify screen.
      endif.

    endloop.</b>
