Functionality of module pull program.

Dear Experts,
I have a question, What is the "functionality of module pull program". Can Any one guide me, What answer should be for this.
With warm regards

Hi
Module Pool program means nothing but the Transaction with number of screens
As you are aware SAp is full of all business transactions which are build with Module pool program
For example take Sales Order
it consists of many screens built with module program
Every module program is executed with an Attached Transaction code
for Sales Order Transaction is the VA01 and the program is the SAPMV45A

You can also check the transaction ABAPDOCU which gives you lot of sample programs.
Also you can see the below examples...
Go to se38 and give demodynpro and press F4.
YOu will get a list of demo module pool programs.
One more T-Code is ABAPDOCU.
YOu can find more examples there.

Require select-option functionality in Module Pool Programming

Hi Gurus,
I am doing a development by Module Pool on Warehouse Management. For that development user require select-option on
screen for entering multiple storage type.
My first question : Is any thing available for directly implement select-option by module pool ?
My Second Question : I have use two text boxes for range and one button for multiple selection and arrange on screen like select-option. then on PAI of that button I call COMPLEX_SELECTIONS_DIALOG FM. Now it is working fine. Now I put some value in it. when I save the values and exit , I want the icon of the button must change from icon_enter_more to icon_display_more. I write the below code for that in PBO of the screen:
 if rtab[] is initial. "RTAB[] is a table for holding values what inputted in popup of multiple selection.
 write icon_enter_more as icon to button. " BUTTON is screen field and it taken as a type C length 4 on TOP module as .
 else. " BUTTON taken on screen as push button.
 write icon_display_more as icon to button.
 endif.
but the icon is not changing dynamically.
If I use ICON_CREATE then one short dump happen describing OUTPUTLEN_TOO_SMALL.
Can anybody please give me the solution.

IN PBO SECTION.

Do we have standard function module or program to activate transformation?

Hi Gurus,
Do we have any standard function module or program to activate transformation in BI system? If yes please let me know or let me know how to proceed with to create custom program to activate transformation.
Thanks,
Manoj

Hi Sven,
Thanks for your help.
Even I am facing the same problem, we didnt want to open the production system to activate the transformation also it take time to transport them every time from development
can you please explain how to use these methods, what parameters to pass
do you have a sample code, it will be of great help.
use this methods
cl_rstran_trfn=>factory
cl_rsds_rsds=>if_rso_tlogo_general~get_instance
l_rsds->if_rso_tlogo_maintain~is_active

Function Module or Program to get where used list

Hi,
I´ve been searching for Function Module or program to get where used list for an object.
I try using the FM 'RS_TOOL_ACCESS' with parameters operation = 'CROSSREF', objectname = 'ZMYPROG', object_type = 'PROG'
and in effect i get the list of object where the program is used, but the list is showed in standard screen.
is there a function or program to obtain the used list for an object but in an internal table?
I'm using version 4.6B.
I checked the function module RS_INFOSYSTEM_CREATE_REQUEST, but i didn't obtain any result, is there a funcion or combination or FM to get the used list?
thanks,
Alejandro

Update TVARV table entries using a Function Module or Program

Hi Gurus,
My requirement is that I have a entry in TVARV table which has a 'low'. We would like to change this value whenever we desire. We are unable to do it via sm30 and se16 as table maintenance access is not permitted in Production environment.
Can you please provide any Function module or program code to do it?
Requirement - User can enter a value into TVARV table by executing a function module or program
Thank you all, will award points,
Priyansh

Hi Priyansh,
Please refer to SAP Help for more information on variant maintenance and more specifically variable values in variants. You can use t/code STVARV for maintaining the variant variables in table TVARVC (Client-Specific Variant Variables).
Note: I suggest to use the TVARVC table instead of TVARV.
If you are looking for Function Modules in the area of Variant Maintenance, then please have a look at Function Group SVAR (t/code SE80).
If you are looking for Function Modules in the area of User Variables in Variants, then please have a look at Function Group SVUV (t/code SE80).
Furthermore, if you are looking for a program to update table TVARVC, please have a look at ABAP: Dynamic Variant Processing with STVARV.
Best eregards,
Sander

Need help in module Pool programming.

Dear gurus
I'm stuck in a step of Module Pool program
Steps i used for enhancement in XK01.
1) i appended a structure in table LFA1 having two fields A and B.
2) then i went to IMG-> Logistic -> Business Partner-> Vendor -> Adoption of Customer's Own Master Data Fields -> Prepare     Modification-Free Enhancement of Vendor Master Record ( Here i created my screen group Z1 without Function Code.
3) then i created below module pool program. of screen 9999 and in layout i added to fields to display A and B which i appended.
PROGRAM ZSNAK_XK01.
TABLES: lfa1.
module status_9999 output.
endmodule.                 " status_9999 OUTPUT
module user_command_9999 input.
endmodule.
4) After this i wen to IMG-> Logistic -> Business Partner-> Vendor -> Adoption of Customer's Own Master Data Fields ->
    Business Add-In: Processing of Master Data Enhancements ( Here i created my implementation on method CHECK_ADD_ON_ACTIVE and added this code
if i_screen_group eq 'Z1'.
e_add_on_active = 'X'.
endif.
5) then i went to   IMG-> Logistic -> Business Partner-> Vendor -> Adoption of Customer's Own Master Data Fields ->
   Business Add-In: Customer Subscreens. and created my implementation on method GET_TAXI_SCREEN where i have written this code.
e_screen = '9999'.
e_program = 'ZSNAK_XK01'.
e_headerscreen_layout = ''.
After activation when i execute t-code XK01 i see my button there after INFORMATION BUTTON when i click on it i get following error.
Incorrect screen type: Screen is incorrectly defined or used.
The attribute screen type with the values 'Normal Screen' and
'Subscreen' determines the use of the screen. If a normal screen is used
   as subscreen or vice versa, an error occurs.
The screen "ZSNAK_XK01" 9999 has, in this respect, an inappropriate screen
   type.
Please guide me
Regards
Saad Nisar.

I think you have defined the screen 9999 as normal screen. go to attributes tab of the screen and make it as "subscreen' (radio button) and activate

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
Endif.

Prabhudas
