Former Member — Wed, 21 Dec 2005 04:05:15 GMT

Hi,

I have a question regarding screen modifications.

I have 2 fields on the infotype screen,first is the listbox,second is one input field.

Based on value of the list box, if 1 the other field should be disabled(grayed out)and for all other values the field should be enabled.

Could u please help as this is a urgent requirement.

This isn't exactly what you're doing, but it's similar:


SELECT-OPTIONS: s_fictr FOR  zzfbud_mig_tot-zf_fictr
                        MEMORY ID fis,
                s_geber FOR  zzfbud_mig_tot-zf_geber
                        MEMORY ID fic
                        MODIF ID cfc,
                s_prof  FOR  zzfbud_mig_tot-zf_profil
                        MEMORY ID bp1
                        MODIF ID cfc,
                s_class FOR  zzfbud_mig_tot-zf_classif
                        MEMORY ID kla NO INTERVALS
                        MODIF ID cfc,
                s_gjahr FOR  zzfbud_mig_tot-zf_gjahr
                        MEMORY ID gjr.
PARAMETERS:     p_test  AS CHECKBOX DEFAULT 'X',
                p_cfc   AS CHECKBOX DEFAULT 'X'
                        USER-COMMAND ucom.
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF screen-group1 = 'CFC'.
      IF p_cfc = 'X'.
        screen-input = 0.
      ELSE.
        IF screen-group3 <> 'OPU'.
          screen-input = 1.
        ENDIF.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

Yes Similar.

I have a module pool program with PBO and PAI, after the user enter the value for 1st field the second field should be either enabled or disabled depending on the value of the field one.

I did the exact way (like what you mentioned), I am able to get the second field disabled when I click enter for the first time after entering some value for the first field. The second field here is getting disabled. Till this point everything looks good. But when click 'Enter' again, the second field is becoming enabled from disabled status. This should not happen until I change the value for the first field.

Am I clear in explaining the question?

Please help.

Thanks.

Kavitha.

It sounds like a data transport problem between the screen and the program. Have you put a break point at the point in the code where you loop at the screen? If you have, what is the value of the variable that you are testing after you press enter the second time? Is it the same as the first time?

Thanks

Do you do the "MODIFY SCREEN"?

yes. please see the code below which i am using.

IF p9918-textt = 'ONE'.

LOOP AT SCREEN.

IF screen-group3 = '002'.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ELSE.

LOOP AT SCREEN.

IF screen-group3 = '001'.

screen-input = '1'.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

what are you doing in PAI.

how many fields are there in your screen.

I am developing a custom infotype in HR. I have designed the screen with 2 fields, the first one is a list box with two values (lets say 1 and 2), the second one is a input field. My requirement is when the user selects '1' for the first field and when he clicks enter, the second field should be disabled. And if the value = '2' then the field should be input enabled.

Thanks.

if list_value = '1'.
loop at screen.
if screen-name = 'SECOND'.
screen-input = '0'.
modify screen.
clear SECOND.
endif.

endloop.

else.
loop at screen.
if screen-name = 'SECOND'.
screen-input = '1'.
modify screen.
clear SECOND.
endif.

endloop.

endif.

Still the same problem.

For the first 'Enter' the second field gets disabled, but if I click enter again, the field is enabling.

Thanks.

See in your PAI, if you are manipulating the value of p9918-textt and when you are pressing ENTER second time, may be this value is no longer ONE.

Re: screen modification

Former Member — Wed, 21 Dec 2005 05:13:51 GMT

yes,it is retaining the value 'ONE',everytime i click enter.

hi,

try with removing quotes .

use

<b>screen-input = 0</b> instead of screen-input = '0'.

One more option is use can assaign fcode to list box,

then whenever you change the list box contexts PAI triggers no need to press enter.

And you can use this fcode in your screen modify logic.

then the problem lies in your code, where you are modifying...

and is it going there where we are checking and modifying screen after you press enter.

check that..

Re: screen modification

Former Member — Wed, 21 Dec 2005 05:16:58 GMT

Can you please post your PAI logic for ENTER and also the code where this table is manipulated in any module?

Re: screen modification

Former Member — Wed, 21 Dec 2005 05:20:26 GMT

I tried with 0 without single quotes,but still the same problem.

Re: screen modification

Former Member — Wed, 21 Dec 2005 05:21:43 GMT

give the code in which you are doing those check under PAI.

Re: screen modification

Former Member — Wed, 21 Dec 2005 05:23:45 GMT

I am looking at this code you posted.


IF p9918-textt = 'ONE'.
  LOOP AT SCREEN.
    IF screen-group3 = '002'.
      screen-input = '0'.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.
ELSE.
  LOOP AT SCREEN.
    IF screen-group3 = '001'.<-- why is this 001 instead of the 002 that you made input 0 earlier
      screen-input = '1'.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.
ENDIF.

and don't use quotes around the zero or one for screen-input.
