Making a field on screen input enabled or disabled

Dear Friends,
Please suggest how can I make a field on my dialog-program screen input enabled or disabled through coding. I understand that the same can be done by setting screen parameters but i wish to do that through programming only.
Regards,
Alok.

Hi Alok,
A field can Enabled or Disabled by setting its attributes.
As it is a element placed on screen and modify the screen you need to modify the screen table.
loop at screen.
screen-group1 = 'SC1'.
Enable:
if screen-name = 'PA_MATNR':
screen-input = '1'.
screen-output = '0'.
modify screen.
endif.
DISABLE:
if screen-name = 'PA_MATNR':
screen-input = '0'.
screen-output = '1'.
modify screen.
endif.
endloop.
Some more Info :
1 --- Active
1 --- Input
1 --- Output
0 --- Invisible
Screen field is displayed, even if Invisible is set statically.
Field contents are displayed.
Ready for input, even if Input is not set statically. However, not ready for input if the Output only is set statically.

Selection screen, dynamic enable and disable of blocks

Hi,
i have several parameters in different blocks.i want to enable one block and disable other blocks depending on the radio button selection. could some one help me on this.
for eg.
radiobutton1. under this text entries for date, time etc.
radiobutton 2. under this text entries for location from, location 2,phone etc.
so, if i select radio button 1 all the remaining text entries under other radio buttons should be disabled. how to do this.
your help would be appreciated.
Thanks,
kranthi.

Hi Kranthi,
I am not sure what you meant by disabling all the selection screen fields. Are you saying ALL the selection screen fields or all fields that don't belong to the selected radio-button.
Anyway, here is a sample code how you manipulate the selection screen. The key options to use are 'modif id', 'at selection-screen output' and 'loop at screen'.
*------------------------ Selection Screen ---------------------------*
SELECTION-SCREEN BEGIN OF BLOCK selscr WITH FRAME TITLE text-000.
PARAMETERS: p_rad1   RADIOBUTTON GROUP rad1 USER-COMMAND a DEFAULT 'X',
            p_rad2   RADIOBUTTON GROUP rad1,
            p_rad3   RADIOBUTTON GROUP rad1.
*-- Selection Screen for radio button 1
SELECTION-SCREEN BEGIN OF BLOCK rad1 WITH FRAME TITLE text-001.
PARAMETERS:     p_date   LIKE sy-datum DEFAULT sy-datum MODIF ID one.
SELECT-OPTIONS: s_uzeit FOR sy-uzeit MODIF ID one.
SELECTION-SCREEN END OF BLOCK rad1.
*-- Selection Screen for radio button 2
SELECTION-SCREEN BEGIN OF BLOCK rad2 WITH FRAME TITLE text-002.
PARAMETERS: p_werks   LIKE t001w-werks MODIF ID two.
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN COMMENT 1(6) text-003 MODIF ID two.
SELECTION-SCREEN POSITION 8.
PARAMETERS: p_chk AS CHECKBOX DEFAULT 'X' MODIF ID two.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF BLOCK rad2.
*-- Selection Screen for radio button 3
SELECTION-SCREEN BEGIN OF BLOCK rad3 WITH FRAME TITLE text-004.
PARAMETERS: p_matnr   LIKE mkal-matnr MODIF ID tri,
            p_verid LIKE mkal-verid MODIF ID tri.
SELECTION-SCREEN END OF BLOCK rad3.
SELECTION-SCREEN END OF BLOCK selscr.
AT SELECTION-SCREEN OUTPUT.
IF p_rad1 = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'TWO' OR
          screen-group1 = 'TRI'.
        screen-input = 0.
        screen-invisible = 1.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
ELSEIF p_rad2 = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'ONE' OR
         screen-group1 = 'TRI'.
        screen-input = 0.
        screen-invisible = 1.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
ELSEIF p_rad3 = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'ONE' OR
         screen-group1 = 'TWO'.
        screen-input = 0.
        screen-invisible = 1.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
ENDIF.
If you want to hide all the, I mean all except the radio-buttons, then simply loop at screen and modify every entry except the radio-button entries to screen-active 0. Something like this.
LOOP AT SCREEN.
IF SCREEN-NAME = 'RAD1' OR
     SCREEN-NAME = 'RAD2 OR
     SCREEN-NAME = 'RAD3'.
ELSE.
    SCREEN-ACTIVE = 0.
    MODIFY SCREEN.
ENDIF.
ENDLOOP.

Making Mandatory fields on Screen and vice versa

Hi,
I've developed a screen on which i've a field say X. Initially when the screen is shown the field is not mandatory as user may or may not enter its value.
But when he enters its value, then i've to make field Y and field Z mandatory also.
For this in PBO i've called a module which would make the necessary screen change.
    LOOP AT SCREEN.
      IF X IS NOT INITIAL.
        IF ( screen-name = 'Y' OR
             screen-name = 'Z' ).
          screen-required = '1'.
        ENDIF.
      ELSE.
        IF ( screen-name = 'Y' OR
             screen-name = 'Z' ).
          screen-required = '0'.
        ENDIF.
      ENDIF.
        MODIFY SCREEN.
    ENDLOOP.
Though the above code makes the field Y and Z mandatory but when the user clears the field X value still it shows them mandatory which i don't want
How can i handle this?
PLZ HELP!

Hi
What everyone described is using code block..
why not you should define it while designing the screen.
on defining the field Input/Output Field Attributes of Y & Z , define program-> input -> Required.
In detail :
INPUT/OUTPUT Field of Y & Z
Attributes
Dict | Program | Display
*Under Attributes -> Program -> Input (drop down list) -select as Required.*Hope it will work fine.

Making material group field in ME22n transaction as Input Enabled

Hi,
I have a requirement in my project, where I need to make the material group field as Input Enabled.
The reason for this being, that after a PO is created, the user might change the material group of the material(using MM02). The new material group must reflect in the already created PO's.
I have searched and gone through the previous threads, which say that it is impossible for new material group to be reflected in the already created PO.
But we can make it as input enabled field, instead of changing the material group, so that user can MANUALLY change it.
I searched and found out that material group cannot be made as Input Enabled field using SPRO settings.
Also there is no BADI or user exit where we can code for it an make it as input enabled.
But there is some internal enhancment point, in the SAP source code, where we can go and do the coding for it. I am sure about it because I have seen such a scenario earlier also.
Can someone help me in finding out the particulare enhancement point where we can code for our field to become Input Enabled?
Thanks in advance.
Ramesh Singh

Not possible - if it is SAP standard field.

How to get the value entered in input enabled field of a list output?

Hi all,
I am developing a program to display list with two input enabled fields . After users enetered the values into these fields I need to do some calculations based on these values and modify the value of another field in the list.
But i couldn't have an idea how to read the values after users enter into these fields.
Please help me on solving this problem? If possible please provide the sample code.
Thanks,
Aravind.

You can enable disable screen fields in at selection screen output event.
And by using loop at screen.
And for changing the values you can do in initialization event.
I Hope you are doing these in Reports.

Short Dump while making a fields as required in BDT object screens

Hi,
I'm making a field as "required" by checking the required button on that field in the BDT screen.
But am getting a short dump when I'm trying to use that screen.
It seems like some data is getting converted to bad format due to this (am not fully sure about it.)
Any idea on this.
Thanks & Regards,
Vipul.

Hi Pinaki,
The entire functionality is working absolutely perfect if I dont check that field as "Required" .
I'm not sure if I'm missing some customising or is it a problem with BDT.
Thanks & Regards,
Vipul.

Custom field in Bid Quote not editable/input enabled/changable

Hai All,
    In the SRM Surrogate Bidding process , PO is generated from the Quotation which corresponds to the bid which has been accepted. Now before generating the PO we need to pass the Ordering vendor address information from the Quotation back to the PO. We added a custom field to the Quotation following Note 672960 - User-defined fields 2 and it is being added to the BASIC DATA TAB in the Header data of the Quotation, but we are not able to enter any values since it is in display mode.
   We then referred Note 809630 - Customer field in bid invitation and bid - How does it work? ( after referring Notes 458591 and 672960), and found that we need to implement the methods MODIFY_SCREEN and MODIFY_MODE_QUOT of the BADI BBP_CUF_BADI_2.
         The MODIFY_SCREEN method works fine, but the MODIFY_MODE_QUOT is not getting called during the Bidding process. MODIFY_MODE_QUOT is already existing in the system as per the Note 822424 - CUF. Customer fields cannot be changed in the bid . Also Function-Pool SAPLBBP_PDH_CUF does not have any calls to the method MODIFY_MODE_QUOT but it has calls for the other 3 methods present in that BADI.
       We would like to know (1) How we can make this MODIFY_MODE_QUOT work? (2) And if it is working, Will MODIFY_MODE_QUOT along with MODIFY_SCREEN make the field in the Quotation Input enabled, and/or (3) Is there any other way by which we could make the field Input enabled, for the Users to enter some values, before they Click the Generate PO button.
Please help.
Thanks,
Ghanesh

Hi Ghanesh and SRM experts,
I went through your link mentioned below and I have the EXACT same issue. I am using SRM 5.5 and I have added a custom field to the quotation item level. I am unable to make this field editable no matter what I do .
1) I have gone through all notes mentioned in your scrap and I have implemented them all .
2) I have added the custom field to INCL_EEW_PD_ITEM_CSF_QUOT and INCL_EEW_PD_ITEM_CSF.
3) I have also implemented BADI BBP_CUF_BADI_2 and I confirm that the method MODIFY_MODE_QUOT is never getting called. MODIFY_SCREEN is getting called , and the value of the flag ET_FIELDS-XINPUT is always 'X'. Still the quotation field is display only.
Your post is dated a few months back. If you have solved this problem could you please let me know how.
Help from anyone who anything about the above will be appreciated.
Thank You .

Ajali Sen

Making a field enabled

Hi all,
In ME22 Transaction, the DOCUMENT DATE (BUDAT) field by default is disabled .
I have to made it as enabled.
Please suggest me how to make the posting date field as enabled
Are their any BADIS or field exits or any way to solve this problem
Regards
Ajay

It can be done by creating transactional variant in the tcode SHD0.
In the field Transaction on SHD0 enter the transactioncode for the screen you want to modify (E.g. VA03)
In the field Variant on SHD0 enter the name you want to give the transaction variant (E.g. ZVA03)
Press Create
Now the screen for the transaction is shown and you can enter default values in the fields of the screen
Press Enter. Now a screen that enables you to make further customizing (Hide, Output only, Invisible,
Mandatory) if the screen fields is shown.
After you have finished customizing the screen press Enter to go to the next screen and exit
to save the Transaction variant.
Check the tcode the field is made enabled.

They have written logic in the sub-screen 200 in PBO.this is reflecting in alll sub-types of 21(alomst 20 subtypes)
module abc_output.
If T001P-MOLGA = 'australia'.
if screen name = 'city'.
screen-input = 'OFF'.
screen-invisible = 'ON'.
endif.
endif.
Now the requirement is that this logic should be modified such that this city should appear in 7 sub-type instead of district.

Enabling custom field in screen after error msg

HI experts,
I m facing problem in enabling screen field in infotype screen. That is, i have added a custom field in std infotype screen and this is shown in enable mode by default. In PA30, im enterig values for all fields in the infotype and press SAVE.
At that time, an error message is thrown by the system. Becoz of this error message, my custom field is changed to disable mode and also gets shrinked.
Can anyone suggest me how to enable my own field in screen even after the error msg returned by the system?

There are two ways to cater such a kind of problem.
either you can enable custom field manually by writing code or
you can change field group.
