obligatory field problem

[Former Member]

Hi experts,

I search google and sdn forums for solving my following problem but I couldn't find anything.

I have an selection screen with 3 obligatory fields.

And this is what I want to do:

If the first obligatory field is filled then the other 2 obligatory fields shouldn't be obligatory anymore.

Otherwise if the 2 last obligatory are filled the first obligatory shouldn't be obligatory anymore.

But how to implement this?

Thx for any suggestion!

My tip for searching terms in Google or SCN would be with Loop at screen,Modif ID,at selection-screen....

HI,

Dont use Obligatory ...u can use At-Selection-Screen and then check which field is INITIAL and display error message of type E ..to enter the next field values

thanks

Hi,

I think you need do like this:

SELECTION-SCREEN BEGIN OF SCREEN 500. 
  SELECT-OPTIONS field1 FOR sflight_wa-connid. 
		  field2 FOR sflight_wa-connid. 
		  field3 FOR sflight_wa-connid. 				
SELECTION-SCREEN END OF SCREEN 500. 

* Handling selection screen events 

AT SELECTION-SCREEN ON field1. 
  IF field1 IS INITIAL. 
    MESSAGE 'Please enter a value in field 2 & 3 ' TYPE 'E'. 
  ENDIF

AT SELECTION-SCREEN ON field2 or field3. 
  IF field2 IS INITIAL. 
    MESSAGE 'Please enter a value in field 1 ' TYPE 'E'. 
  ENDIF

Hi,

Try this

parameters: field1(10) type c,
                    field2(10) type c.


At selection-screen output.

if field1 is initial. 
if field1 is initial and field2 is initial.
message e398(00) with 'Enter field2' .
endif.
endif.

if field2 is inital.
if field2 is initial and field1 is initial.
message e398(00) with 'Enter field1' .
endif.
endif.

Hello,

You can switch OBLIGATORY to NON-OBLIGATORY at event AT SELECTION-SCREEN.

Check screen field is initial or not if it is initial then make other to fields OBLIGATORY = 1 using LOOP at screen.

Check if this can help.

Thanks,

Hi,

Check this.

PARAMETERS: p_field1 TYPE char10 ,
            p_field2 TYPE char10 ,
            p_field3 TYPE char10 .

AT SELECTION-SCREEN.
  if p_field1 is INITIAL and
     p_field2 is INITIAL and
     p_field3 is INITIAL.
    MESSAGE 'ENter' TYPE 'E'.
  ENDIF.

AT SELECTION-SCREEN OUTPUT.
  if p_field1 is NOT INITIAL.
    LOOP AT SCREEN.
      if screen-name eq 'P_FIELD2' or screen-name eq 'P_FIELD3'.
        screen-required = '0'.
        MODIFY SCREEN.
      ENDIF.
      ENDLOOP.
  ENDIF.
  if p_field2 is NOT INITIAL.
    LOOP AT SCREEN.
      if screen-name eq 'P_FIELD1' or screen-name eq 'P_FIELD3'.
        screen-required = '0'.
        MODIFY SCREEN.
      ENDIF.
      ENDLOOP.
  ENDIF.
  if p_field3 is NOT INITIAL.
    LOOP AT SCREEN.
      if screen-name eq 'P_FIELD1' or screen-name eq 'P_FIELD2'.
        screen-required = '0'.
        MODIFY SCREEN.
      ENDIF.
      ENDLOOP.
  ENDIF.

  START-OF-SELECTION.

Hi,

you need to put logic at AT SELECTION-SCREEN .

don't declare field as obligatory.. instead of this

SELECTION-SCREEN BEGIN OF BLOCK blk WITH FRAME TITLE text-001.

PARAMETERS : p_miscpl TYPE t5uba-bplan ,

p_optpl TYPE t74fl-levl1 ,

p_month(2) TYPE c .

SELECTION-SCREEN END OF BLOCK blk.

AT SELECTION-SCREEN .

IF p_miscpl IS INITIAL.

IF p_optpl IS INITIAL AND

p_month IS INITIAL.

MESSAGE ' field2 and field3 are mandatory' TYPE 'E'.

ELSEIF p_optpl IS INITIAL OR

p_month IS INITIAL.

MESSAGE ' field2 and field3 are mandartory' TYPE 'E'.

ENDIF.

ELSE.

IF NOT p_optpl IS INITIAL AND

NOT p_month IS INITIAL.

MESSAGE ' field1 is mandatory' TYPE 'E'. sorry not m andatory

ENDIF.

ENDIF.

its working absolutejy fine......

let me know if u have problem

Thanks

try this way:

don't use obligatory statements.

and at selection screen event . give proper error messages as required.

Hi,

firstly thank u ALL for your hints!

@Amit, Rimpa, Faisal and Sumanth:

Thanks for these hints!

So, now I know different ways to solve this problem!

@ Vikred and Ashu

Actually, your coding solved my problem!

Especially Ashus code was very useful!

@ Balu

Very nice tip but unfortunately it didn't work for me.

E.g. this line :

AT SELECTION-SCREEN ON field2 or field3.

doesn't work because it says that after field2 there should be a point.

@Augustrian and Nitwick:

Your hint is another way to solve my problem!

In the end I implemented like Vikred and Ashu advised me:

Sorry, Messages are in German..

SELECT-OPTIONS: 
so_vbeln FOR likp-vbeln,
so_vstel FOR likp-vstel,
so_lfdat FOR likp-lfdat.

AT SELECTION-SCREEN.
  IF so_vbeln IS INITIAL AND
     so_vstel IS INITIAL AND
     so_lfdat IS INITIAL.
    MESSAGE 'Bitte Lieferung ODER Annahmestelle und Liefertermin ausfüllen!' TYPE 'E'.

  ELSEIF so_vbeln IS INITIAL.
    IF so_vstel OR so_lfdat IS INITIAL.
    MESSAGE 'Bitte die Pflichtfelder Annahmestelle und Liefertermin ausfüllen!' TYPE 'E'.
    ENDIF.
  ELSEIF so_vstel AND so_lfdat IS INITIAL.
    IF so_vbeln IS INITIAL.
    MESSAGE 'Bitte Lieferung ausfüllen!' TYPE 'E'.
    ENDIF.
  ELSEIF so_vstel OR so_lfdat IS NOT INITIAL.
    IF so_vbeln IS NOT INITIAL.
    MESSAGE 'Bitte Lieferung ODER Annahmestelle und Liefertermin ausfüllen!' TYPE 'E'.
    ENDIF.

  ENDIF.

I appreciate your help!

Best Regards,

Zaya
