How to deactivate the screen fields dynamically in Module Pool Program?

Hi guys,
How to activate & deactivate the screen fields of a module pool program
dynamically through program. Like Change mode and display mode in a single
screen.

Hi,
Make use of a Variable,say gv_flag, for both Activate and Deactivate functionalities. As many times you hit the same button, change this variable value. For example, let us say first time you hit this button, assign value 'X' to this variable. Second time you hit this button, assign value ' ' to this variable. In PBO based the variable value you have to Activate and Deactivate.
PBO.
if gv_flag = 'X'. " Activate
    loop at screen.
      if screen-fname = 'ITAB1-MATNR'.
         screen-input = '1'.
         modify screen.
      endif.
    endloop.
elseif gv_flag = ' '.   " Deactivate
      if screen-fname = 'ITAB1-MATNR'.
         screen-input = '0'.
         modify screen.
      endif.
    endloop.
endif.
PAI.
case sy-ucomm.
     when 'ACDC'.   " Activate/Deactivate
         if gv_flag = 'X'.
           gv_flag = ' '.
         else.
           gv_flag = 'X'.
         endif.
endcase.
thanks,

i want to have input search help as if i select sales document type then corresponding sales organizations should appear
This would be quite opposite of what h_vakz does. h_vakz gives Sales document based on Sales org..and you want vice versa. Create a simple SH with
selection method : TVAKZ
AUART as importing only
VKORG as exporting only. So when you enter an AUART you get all VKORG it is defined in. I'm not aware of a standard search help which matches the requirement. If anybody does please help me.
i have header data (only mandatory fields),items data,partner data(all mandatory fields)
and when i select all the header data the search help that is on the material number and partners role and number should appear corresponding to that header data
You will have to be more specific sir..
not able to apply please guide someone
As for that just mention them in SCREEN->ELEMENT LIST->REFERENCES

How to track changes to fields in a Module Pool Program

Hi Experts,
I have one requirement to track the changes to some fields used in the Program, The fields for tracking the changes will be maintained in a table T1, this will be changed dynamically.
There are many screens in the program and many fields in each screen.
1. How to do the coding for tracking the changes, the code should track all the changes to the fields maintained in the table T1.
Thanks in Advance.
Baburaj

Hi Baburaj,
The table logging concept will helpful for this requirement.(Tcode: scu3 --> give table name --> u can find changes for all fields).
Make use of concept change documents (auditing purpose used) --> CDHDR,CDPOS tables.
If you want to track changes to your own program, You need write some API to store the data.

Want to know the screens associated with a module pool program ??

Hi,
I have an M type program (module pool), say SAPMF05M. I want to
1) see which transaction code initiated it ??
2) see the screens associated with it ??
how do i achieve this ?? I know just the program name !!
thanks

Go to SE80, make sure "program" is in the object list box, enter the program name in the field underneath the object listbox and hit enter. You will see a bunch of folders in the tree structre. There will be one for screens and one for transactions.
Please remember to award points for helpful answers. Thanks.

How to Read the Screen Fields after a Transaction ?

Hi all,
I am working on the Transaction 'O4K_LICENSE'. After the transaction is run, it generates an Internal License number which is displayed on the screen. I tried using 'GET PARAMETER', but as the CALL TRANSACTION is called within a loop, the SAP Global memory is not getting refreshed and iam getting the same value for every loop for the Internal License Number.
Is there any function Module other than DYNP_VALUES_READ to get the screen field values? I tried using the above function module, but in vain and it is not getting any values.
Warm Regards,
Vijay.

Well .... let me explain this very clearly.
The table OIHL has a composite primary key which is the combination of "External License Number" and "Internal License Number". The latter is generated after running the O4K_LICENSE transaction.
Moreover, iam attaching every record with a record generated in the program. Now, the same User(ERNAM) can create records having the same External License Number.
For example:
If i created a record yesterday with an external License Number 123, then say an internal lic no of 3 is assigned to it.
If i Create another record today with the same external lic no of 123, and an internal no of say 20 is attached to it, then i donot have any criterion to select the one which i have created today, as it fetches both the records.
To add to the worst, there is no timestamp field also.

How to validate the field values in module pool program?

Hi Guys
 I am working with module pool programming.
 Here I want to validate the fields like below.
 with out filling all the fields if I click SAVE option it has to show a message that all fields has to be filled. This can be done by checking all the fields individually.
 I think it can be done through LOOP AT SCREEN ......ENDLOOP. sequence.
 If it is possible, can anyone help me?

You need to write the Module in between the CHAIN and ENDCHAIN statment in SE51
If you send a warning or error message from a module <mod> that you called using a FIELD statement as follows:
CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1>.
FIELD: <g1>, <g 2>,...
MODULE <mod2>.
ENDCHAIN.
all of the fields on the screen that belong to the processing chain (all of the fields listed in the field statements) are made ready for input again. Other fields are not ready for input. Whenever the MODULE statement appears within a processing chain, even if there is only one FIELD attached to it, all of the fields in the chain (not only the affected field) are made ready for input again, allowing the user to enter new values. If the fields in the processing chain are only checked once, the PAI processing continues directly after the FIELD statement, and the preceding modules are not called again.
Look at the DEMO program DEMO_DYNPRO_FIELD_CHAIN.

Calling search helps dynamically in module pool program

Hi Experts,
I have created two search helps. I need to call these search helps in my module pool program dynamically for a single field (i.e ZMATNR).
you might be known... if it is a single search help, we can assign that in field attributes.
But here... I need to call different search helps for a single field based on the condition.
Pls help me.
Thanks
Raghu

Hi,
Use the below function module and pass the search help created in search help field according to the condition.
Process on Value-request.
if condition = A.
call function " F4IF_FIELD_VALUE_REQUEST"
TABNAME           =
FIELDNAME        =
SEARCHHELP     = "Mention search help created
Elseif Conditon =B.
call function " F4IF_FIELD_VALUE_REQUEST"
TABNAME           =
FIELDNAME        =
SEARCHHELP     = "Mention search help created

Regards,
Anil kumar G

Hi Anil..
We can change the Text of a Pushbutton dynamically.
For this:
1. Declare a Global variable with the Same name as the Button in TOP include
Eg: Data: Button1(30).
2. In the PBO module of the Screen assign the Text to this variable:
 Eg:
 Module set_text OUTPUT.
 Button1 = 'This is the text'.
 ENDMODULE.

How to restrict the screen field TASK in SWI2_FREQ tcode

Hi All,
The user who ever has authorization for this transaction code is able to access all the task types irrespective of SAP modules from back end.
The concern is that the task type of any module should not be visible for un-authorized people.
In the front end only the authorized people can see work flow items (mail's) and it's according to business requirement.
Is there any solution?
If Yes, Pls let me know .
Thanks
Heena.

Hi Heena
I'm afraid that you won't find any standard SAP Authorization object that can help you here,
You might how ever be able to solve it with HR Structural authorization, but be carefull here, if you activate the structural authorization check you migh be looking at a large SAP Security Project.
I would usually not recommend that you give access to this transaction to other than your workflow administrators. But if you need to you might be able to create transaction-variants with fixed tasks, and the assign thoose to a t-codes, to which you grant access

Delete field dynamically in Module pools

Hi,
Is is possible to delete or add a particular field at runtime.
I can make it invisible but is it possible to remove it.
Thanks in advance.
Aditya

The typical approach would be to define, say, 20 input fields in the screen, and hide those you don't want. If you name the fields carefully, you can make the coding more elegant e.g. something like this snippet (not syntax checked):
    loop at screen.
*" Name of screen fields is something like gs_9999-email_01, gs_9999-email_02 etc
      split screen-name at '-' into l_prefix l_suffix. "get email_nn in l_suffix
      l_char_2 = l_suffix+6(2). "get number from end
      if l_char_2 co '0123456789 '. "looks like a number...
        l_numc_2 = l_char_2.
        if l_numc2 > gs_9999-lines_to_show. "how many you want on screen
          screen-active = gc_screen_off. " constant = '0'
        endif.
        modify screen.
      endif.
    endloop.
