Custome module pool creation

Hi All,
I have a requirement to create a module pool for maintaining data for some custom tables I created in SAP.
I'd like to ask what the quickest way to create a module pool for the above is. I have been able to create maintenance screens using the extended table maintenance tool but there is a requirement for a more user friendly holistic approach.
Any helpful suggestions will be greatly appreciated.
Regards,
Andy.

Do like below
if ok_code = 'MODI' . " for your modify button
call transaction ' you transaction name '.
now
if sy-ucomm = 'SAVE' or 'EXIT' or 'BACK' or 'CANC' .
call screen 'your basic screen no.'.
endif.
endif.

Save a variant in a custom module-pool.

Hi all,
i hope there is someone that can help me.
My problem is: i've to save a variant in a module-pool custom SAPMZ...ecc.
Is there a function module or a routine or some specific ABAP istruction to save a variant?
I ask this because in my custom module-pool i've insert input field in main dynpro.
Thanks a lot,
regards,
Alex.

Please use below code it works for me:
What I did was copy the function group SVAR. When it asked what function module to copy just select
'RS_VARIANT_SAVE_FROM_SELSCREEN' and renamed it to 'ZS_VARIANT_SAVE_FROM_SELSCR'.
DATA: lv_screen LIKE sy-dynnr.
CLEAR: t_rkey, t_screen.
REFRESH: t_rkey, t_screen.
t_rkey-report = sy-repid.
APPEND t_rkey.
t_screen-program   = sy-repid.
t_screen-dynnr     = '0101'.
t_screen-type      = 4.
APPEND t_screen.
lv_screen = '0101'.
EXPORT lv_screen TO MEMORY ID 'MZ_COMISSION_REPORT_F02_SCREEN'.
CALL FUNCTION 'ZS_VARIANT_SAVE_FROM_SELSCR'
    EXPORTING
      curr_report          = sy-repid
      vari_report          = sy-repid
    IMPORTING
      variant              = w_variant
    TABLES
       p_screens           = t_screen
     p_sscr               = t_selctab
     p_vari               = t_vari
    EXCEPTIONS
      illegal_variant_name = 1
      not_authorized       = 2
      no_report            = 3
      report_not_existent = 4
      report_not_supplied = 5
      OTHERS               = 6.
t_rkey-variant = w_variant.
MODIFY t_rkey INDEX 1.
CALL FUNCTION 'RS_RWSET_SAVE_VARIANT'
    EXPORTING
      rkey    = t_rkey
    TABLES
      selctab = t_selctab.
Then in program LZSVARF07 function save_as_variant find where it's transfering the screen.
READ TABLE variscreens WITH KEY dynnr = sy-dynnr.
IF sy-subrc NE 0.
    IMPORT lv_screen FROM MEMORY ID 'MZ_COMISSION_REPORT_F02_SCREEN'.
    IF lv_screen IS INITIAL.
      variscreens-dynnr = sy-dynnr.
    ENDIF.
ENDIF.
PERFORM fill_varidyn TABLES p_dynsfields
                       USING $rkey space. "Kein import von DYNSFIELDS
Good luck!

Triggering Workflow from Custom Module pool

Hi,
I am trying to trigger my workflow from my custom module pool using the function module "SAP_WAPI_START_WORKFLOW". I am passing the following parameters for the above function module
TASK, LANGUAGE, DO_COMMIT, USER and INPUT_CONTAINER
but, it is returning the following message
"You are not one of the possible agents of task 'WS90100020'"
Please suggest a solution for this problem?
Regards
Sujith P. Soman

Hi,
A better way would be to trigger your WF using an event and calling SAP_WAPI_CREATE_EVENT. But if you want to start it directly then if you are calling this FM in dialog you need to be a possible agent. The easiest is if you jsut make it a general task so anyone can start it.
In PFTC, open your WF goto Additional Data -> Agent assignment -> Maintain. Click on 'Attribnutes' and select 'General Task'.
Also run SWU_OBUF afterwards to synch all buffers before testing your FM again.
Cheers,
Mike

Custom module pool + Amount field decimals display same as standard screen display

Hi All,
Requirement: A custom module program screen field has to be designed which displays decimal values of amount fields same as amount fields in standard screen.
Standard screen behavior: If the standard screen fields are observed, they refer to data elements WRBTR or AZSOL_F05A (transactions FB50/FB03/FB01). However, number of decimal places that are visible on screen are dependent on the currency that is provided.
Both the data elements have 2 decimal places.
For currency USD two decimal places are displayed - in TCURX - decimal places are two.
For currency JPY or CLP - zero decimal places are displayed - in TCURX - decimal places are zero.
i.e., even though the screen field refers to data element or domain that has the characteristic to show 2 decimal places, based on currency, decimal places are adjusted.
I would like to know how this is happening on standard screen fields.
Solution Required for: How to make the custom screen amounts to display same number of decimal places as standard screen amount fields.
P.S: Before posting the query here, research has been done in SDN and other places. It has been identified that quantity fields adjustments are discussed. However for amount field even though discussed earlier, did not reach a conclusion.
I would like to get a solution for this one.
Thanks in advance.
Goutham.

Thank you all for taking time to take a look at this query.
This issue has been resolved.
Resolution: If the standard transactions (FI transactions in specific) are observed, whenever there is a field that displays amount value, there will be a corresponding field (may not be beside the amount field, somewhere on the screen or in the same sequence of screens) where the currency key value would be entered.
For instance, if you look at FB50 - there is field on top for the user to input currency key value (like USD or CLP or INR).
When any amount field is declared - this currency key field is provided as the reference field in the screen attributes of the amount field.
In short, in the custom module pool program, provide a field that holds currency key value and use this field as reference field for the amount fields.
Do repond to this thread if the resolution is not clear.
Thank you all once again.
Goutham.

Custom Module Pool...

Hello SDN ABAP Community,
I researched this question on the web and in SDN before posting this because I would like an up-to-date understanding of best way to do this.
I have a need to write a custom module pool. It has been a while since I have been to class. I need to get figured out how my naming conventions will work for all the pieces of the module pool (SE51, SE41, pieces of the SE38 module pool).
I seem to remember the teacher saying that the way that SAP allows for customer created module pools was to set the 5th character of the name to 'Z'. eg- sap would use SAPMPetc. customer would use SAPMZetc.
From my searching of web I found following naming standards...
Module pool                             - SAPDY* SAPDZ*
Module pool for dialog               - DY* DZ*
INCLUDES                              - SAPMY* SAPMZ*
Module pool for screens            - MY* MZ*
INCLUDES                              - MP9*
Module pool for info types         - MP9*
INCLUDES                              - SAPFY* SAPFZ*
Module pool for subroutines      - FY* FZ*
INCLUDES                              - SAPUY* SAPUZ*
Module pool for update program - UY* UZ*
INCLUDES
From searching SDN I found following link for ABAP objects, but I am needing for module pool.
http://help.sap.com/saphelp_nw04/helpdata/en/92/c2b084bc1d11d2958700a0c94260a5/frameset.htm
So my question... is there any SAP resource that I can look at to see SAP naming conventions for customer created module pool with SE41, SE51 and SE38?
Thank you,
Dean Atteberry.

Hi Dean, here you can take a look at SAP´s official customer name ranges for all objects, including Module Pool: http://help.sap.com/saphelp_nw04/helpdata/EN/2a/6b0b1f547a11d189600000e829fbbd/frameset.htm

Module pool creation of new button

I have to aad 1 modif button in a screen the condition is like this as i ckick on that modif button it should go to some given transaction and in that new transaction screen if i click to save, back(F3),EXIT(SHIFT+F3) or cancle (F12) it turns over then automatically on the first screen from which it came.

Do like below
if ok_code = 'MODI' . " for your modify button
call transaction ' you transaction name '.
now
if sy-ucomm = 'SAVE' or 'EXIT' or 'BACK' or 'CANC' .

User Decision in a Module Pool

Hello Guys,
I am relatively new to SAP workflows. I am implementing a solution here and I have mixed feelings about the design. I would love to hear some advice on how to proceed or some reassurance that I am going in the right path.
Requirement:
If a Requeust (say Material Creation) is created by the Initiator in my Custom Module Pool program, the workflow is triggered and sent to the Approver.
The Approver should View the Request by executing the workitem from his Inbox which will in-turn call the Module Pool Program.
From there the approver will have two options either to Approve or Send Back.
I have designed my workflow like this...
          View Request (Activity)
                  |
          Aprrove / Reject (User Decision)
   5. I am marking the 'View Request' activty as complete from my Dialog Program so as to make the workflow come to the User Decision step so that I can pick one and execute form the Module Pool. I have a bad feeling that it might not be a standardized method. If not, then how shall I proceed.??

From my point of view the decision step is completely unnecessary (or alternatively I am missing a point here). What is the role of the decision step in the process?
If you have some kind of approval, you should be able to handle it with a one single workflow step. There is no "standard way" of doing things, but there are best practices. If you take a look to any of the SAP standard workflows, they normally work like this (let's take a leave request as an example):
1. Approver clicks the "Approve leave" work item from his inbox
2. This will open the leave request approval application
3. Approver clicks the approve button.
4. Clicking the approval button updates the leave request status to approved in the database and at the same time completes the "Approve leave" work item, and thus the workflow will continue.
Everything is handled with a single step and there is no need for some kind of sequential decision step.
Even better would be that when you click the approve button, you would trigger an event REQUEST.APPROVED of your possible business object instance, and your task would be waiting for this event. The event would complete the even, and thus you would not need to use SAP_WAPI_WORKITEM_COMPLETE (=your application/module pool does not need to know anything about the workflow (=work item ID) - it would just trigger the event for the request). The best approach is to separate the business logic / application from the workflow, if you have a possibility for it (and if you are building something from scratch, then you have all the possibilities for this).
Kind regards,
Karri

Module Pool Selection Screen

The user wants the custom module pool selection screen to look like a list selection screen. Meaning that they want to have the multiple selection box come up at the end of the field. I don't think that this is possible but maybe someone has some ideas

Use code like the following in your TOP include.
Note that we have defined screen 500 in the code.
Now in your transaction code for this module pool set this as the openingscreen. Please revert in case of any clarifications.
Code.
=AF---
selection-screen : begin of screen 500 as window.
selection-screen : begin of block abc with frame title text-001.
select-options : s_bukrs for mseg-bukrs no intervals no-extension
obligatory.
parameter : p_postdt like mkpf-budat obligatory.
select-options : s_vendor for mseg-lifnr.
selection-screen : end of block abc.
selection-screen : begin of block def with frame title text-002.
parameter : c_fore radiobutton group g1 default 'X',
c_back radiobutton group g1 .
selection-screen : end of block def.
selection-screen : end of screen 500.
at selection-screen.
if sy-ucomm = 'CRET'.
perform get_data.

How to create transaction or screen variant for custom tcode in module pool

Hi,
I have one module pool program with custome tcode ,i want to create transaction or screen variant for this tcode.Next time when we run this tcode we need a variant for this tcode.
I tried by using of SHD0 but it is working only for standred tcodes.Is there any possibilty please help me.
thanks,
Lavanya.

Hi,
you created a Custom Tcode for ur module pool Pgm..if u execute the Tcode in the output screen give the input details and press Save Option then variant will be created. Then you can use that variant.
otherwise.. while creating a Tcode..
select an option for Tcode type Tranasction With variant ..there u will provide the variant for ur Tcode ( which is already created ).

How to use module pool program in my custom report?

Hi,
I am developing a custom report in abap. I want to fetch data from a standard module pool program.I want output of this standard module pool program to be used in my standad report.Submit cannot be used with module pool programs. How can i do this?Can u please suggest?

HI friend,
For this you can directly use the table fields i.e. each and every module pool screen fields will be having the table name along with its fields (which you can see by double clicking the field and selecting technical settings button) and since it is a standard module pool program that will get populated directly. So you can get the screen field values directly from the table. I think this will help. Please try and let us know wheather it is solved.
Thanks and regards,

Problem in custom infotype module pool

Hi experts,
I have created custom infotype using PM01 where i am showing fields Basic and HRA. When I enter the value for Basic, automatically the calculation for HRa should be done depending on formula. Also, the HRA fields should be only output field. When I do the changes in the module pool PBO and regenerate the object , the changes I made get disappered. Do I have to create Z of the includes. If so, how to assign it to the infotype? Please help me to solve this problem since its urgent.
Thanks in advance.
Proper solution would be rewarded.
Ujjwala

C
This is the flavour of Infotype.
When you regenerate the Infotype, you are again reassigning the Chanrecterstcis of your Infotype. so the Existing will get regenerated with the Standard Code.
To avoid this what I suggest you is.
After finishing the Regeneration then edit the Module pool of the Infotype basically Screen 200 then add your code and Activate it there itself. Hope you got it.
If you again Regenerate it you loose your Code.
If you have further Questions please let me know.

Custom field added in Module pool is not reflecting in SRM Shopping cart

Hi all,
I have to add a custom field for Plant in the Ship-To address subscreen(BBPSC01) in Shooping cart in SRM.
I have added the field in the program "saplbbp_sc_ui_its" in screen 310.
But I think need to write the HTML code/Java script in HTML template to trigger the code from module pool.
As I am new to this scenario, can anyone please let me know the procedure to follow.
Thanks,
Rakesh.

Hello Anubhav,
If your new customer fields are not displayed dynamically, re-generate Dynpro concerned using report BBP_DYNPROS_GENERATE.

Customer Control in screen painter in Module pool - work like container?

Customer Control option in screen painter in Module pool - work like container?
is it true? How?
Is like any work area or what?
what is the excat use of that option?
regards.

Hello,
In screen painter ,custom control is used to define the control area on the screen.Just click on that and make your own container area.When you create an ALV grid or TEXT EDITOR or any other control,it will get attached to the screen in that area through the custom container.
Name the container area as say 'CONTAINER'.(in capitals.)
When you actually create the custom conatiner programatically,you should give the container area name.ie.
Data : cont type ref to cl_gui_custom_container.
Create object cont
exporting
parent = 'CONTAINER'.
Now,this container that you created-cont is attached to the screen in the area defined by CONTAINER.

Beejal
