SRM 7 - How to make a custom field dynamically retrieved trigger a refresh?

Hi all,
we're working on a brand new installation of SRM 7.
For contracts and purchase order, we created an enhancement on the webdynpro that manages header document data; in such view, custom fields are obtained dynamically and populate a Transparent container; by code, some tray group visually all the custom fields related to a specific section.
Now, the task is quite general; some of these "dynamically retrieved" fields should refresh, when populated, the view.
That is to say, in our context, that some custom field should automatically trigger the WDDOMODIFYVIEW method (which has been extended via overriding with an enhancement) when a value is inserted.
This would be a simple task if the field is explictly visible in the layout screen, since I could easily associate an event to the field itself.
But, since these custom field are automatically extracted in the WDDOMODIFYVIEW method, we don't know how to manage these field's behavior, e.g. after an input value has been inserted.
Each dynamic custom field is a type ref to cl_wd_uielement; we wonder if we have a way to associate an event (e.g., onEnter) to such an element.
Thanks in advance for any suggestion or help you will give us
EDIT: I guess this could not be the best section for such a kind of question ... I'd gently ask moderators eventually to move the thread to the Webdynpro section, if necessary. Thanks in advance.

Closed. I opened a thread on this topic in a more convenient section of SDN forums (Specifically, web dynpro abap). Thanks anyway:)

How to make added custom field Delta mechanism work for LO Cookpit?

We appended a new custome field into extraction structure of the LO Cookpit datasource 2LIS_02_ITM through RSA6. And then run CMOD to write the exit code to populate the value and it works fine. But after we read Roberto's Weblog:
/people/sap.user72/blog/2005/02/14/logistic-cockpit--when-you-need-more--first-option-enhance-it , find the enhancement we did can't make the Delta mechanism works if only this new field gets changed in a record, and the change cannot be reflected on BW.
In order to make the Delta mechansim works, one option is to append the custom field into one of the LIS Communication Structure MCEKKO of 2LIS_02_ITM extraction structure and then write the enhancement code to this LIS Communication Structure. In this way, the custom field can be treated like standard field that whenever it gets changed, the Delta mechanism or the user exit will be triggered. The enhancement for this LIS Communication Struture is LEINS001.
Now we've got two problems when doing the above enhancements of the LIS Communication structure:
1. Maintain extraction structure problem in LBWE:
We added a custom field, e.g., called ZZZ in LIS Communication structure MCEKKO (Purchasing Document Header) by creating a new custom append structure and add the field ZZZ into it, then activate the new append structure, but get warning msg like "Field name DUMMY is reserved (Do not use structure as include in DB table)".
We do find a field called DUMMY in the structure MCEKKO. How to get rid of the warning msg and successfully activate the new custom append structure with the new field ZZZ?
You could say that we can ignore the warning msg, but why the new custom field appended can not be seen from the right side pool of the Maintain Extract Structure in LBWE? We need to make the new custom field shows up in the right side pool and then drag it over to the left side frame and to activate the extraction structure to change it. But now it doesn't show up in the right frame pool!
2. Refer to Sanyam's weblog
/people/sanyam.kapur/blog/2005/04/30/custom-fields-and-bw-extractors-making-a-mixed-marriage-work-part-ii, there is a sample code inside this article which tells us how the sample code looks like to write this LIS Communicaton structure enhancement to make the Delta mechanism works, below is the code we modified to suit our needs, but don't know if it would work?
DATA: i_t_ekko LIKE ekko OCCURS 1 WITH HEADER LINE.
DATA: ebeln LIKE ekpo-ebeln,
 it_ekko TYPE TABLE OF ekko WITH HEADER LINE,
 old_val(50) TYPE c. "For storing the value from the Field Symbol
FIELD-SYMBOLS <fs> TYPE ANY TABLE.
CASE zeitp.
WHEN 'MA'. "When creating a purchase order
 MOVE '(SAPLEINS)T_EKKO[]' TO old_val.
 ASSIGN (old_val) TO <fs>.
 i_t_ekko[] = <fs>.
 LOOP AT xmcekko.
 ebeln = xmcekko-ebeln.
 IF xmcekko-supkz = '1'. "Old Value ?
 SELECT SINGLE * FROM ekko INTO it_ekko WHERE ebeln = ebeln.
 xmcekko-ZZZ = it_ekko-ZZZ.
 ELSE. "New Value ?
 READ TABLE i_t_ekko WITH KEY ebeln = ebeln.
 xmcekko-ZZZ = i_t_ekko-ZZZ.
 ENDIF.
 MODIFY xmcekko.
 ENDLOOP.
EndCase.
Share your ideas and we will give you reward points!

Hello Kevin
We have exactly the same problem. Did you solve it? If you did, could you please tell us how you did it? We neither see our field in LBWE. Our field is a Z field from a Z table.
I hope you could help us. We just have this issue to finish our project.
Thanks a lot in advanced

If you have BADI implimented for custom tabs then you can do this in method ME_PROCESS_PO_CUST~FIELDSELECTION_ITEM
lv_changeable = im_header->is_changeable( ).
LOOP AT ch_fieldselection ASSIGNING <fs>
 IF lv_changeable IS INITIAL.
 <fs>-fieldstatus = '*'. " Display
 ELSE.
 <fs>-fieldstatus = '+'. " Change
 ENDIF.
endloop.

i have created a custom infotype 9004 in which the custom field contain the code values, and the text of this code values are maintained in another ztable.
when i am viewing this infotype in Ad hoc query i am able to see this fields as only value fields and hence i am unable to get text for this field i.e when we right click on this field only the value option is enabled and the text option is disabled, both these options are enabled in some other standard fields like pernr(personnel no), persg(employee group),persk(employee subgroup).

Assign you table of text as a table text to the data element/domain of your custom field or thru external key on your infotype.

Which trigger are you using to do the "getting saved automatically'?
Does this trigger fire before the trigger that is making the field mandatory?

Regards,
Ajit

Dear Deepak,
Thanks for the clarification.
But, as far, I have understood the query - it is very simple and that is..
Whenever one creates a Sales Order (T.Code: VA01), Parameter: Sales Office needs to be mandatory (for all Sales Order, irrespective of Customer Account).
Until-unless, user won't enter the parameter: Sales Office, System will not lead to next page (now, here we need to enter Customer/ material etc...).
I have answered the query, in this regards, only.
Best Regards,
Amit.
Note: Pls. correct me, if I am wrong. Thanks for everyones guidance.

How to populate a custom field of a Std. SAP Tx with BAPI usage 2 Load data

Hi Experts,
For instance, I created a custom field (say, custom_field_1) on a screen of standard SAP tx(say, ME21N) by using screen exit. And in order to populate the data into it (custom_field_1), will use the Function user exits of this Tx(ME23N).
1) In next step, Where Where I have to add this field, apart from appending the same custom field in EKKO/EKPO table or any other related table; Extending the corresponding IDOC or creating a new Custom ÍDOC type? like What about BAPI?
2) If I got a text file with the data (including the data for this custom_field_1 too) and I have been asked to load it into SAP, then, I decided to use BAPI (say, BAPI_PO_CREATE or CREATE1) to create the data, So, How to handle this custom field, I mean, In which BAPI structure I have to pass this custom_field_1 data? ( Iguess, for some BAPIs EXTENSIONIN structures are provided, sorry if am wrong!)
Thank you.
Edited by: SAP ABAPer on Feb 21, 2009 7:40 PM

for example if you added field in the VBAP table then you can pass the custome field values like below
     move 'BAPE_VBAP' to lwa_extension-structure.
      lwa_bape_vbap-vbeln = lwa_final-vbeln.
      lwa_bape_vbap-posnr = lv_posnr.
      move lwa_final-yyslotid to lwa_bape_vbap-new custome field.
      move lwa_bape_vbap to lwa_extension-valuepart1.
      append lwa_extension to lt_extension.
      clear lwa_extension.
      move 'BAPE_VBAPX' to lwa_extension-structure.
      lwa_bape_vbapx-vbeln = lwa_final-vbeln.
      lwa_bape_vbapx-posnr = lv_posnr.
      move 'X' to lwa_bape_vbapx--new custome field.
      move lwa_bape_vbapx to lwa_extension-valuepart1.
      append lwa_extension to lt_extension.
      clear lwa_extension.
call function 'BAPI_SALESORDER_CHANGE'
        exporting
          salesdocument    = strcture
          order_header_inx = strcture
        tables
          order_item_in    =strcture
          order_item_inx   = strcture
          schedule_lines   = strcture
          schedule_linesx = strcture
          extensionin      = lt_extension.

How to add a customer field or extn coll in the tab1&2&3..of a UDO doc?

Hi Experts,
Does anybody know how to add a customer field or extn collection in the unused tabs like tab1&2...in a UDO document?
Thanks for your reply in advance.
Thanks & Regards,
David

Hi Subhasini - 
It seems you have discovered that adding an extension field to the Project Suppliers collection is not possible; many of the collections in E-Sourcing do not support extensions and, even when they do, typically, the table view of the data cannot be changed to show the extension value (it would only show on a "details" page, for example. 
The solution that you have proposed may work, although I think there is a slight mistake in your logic. I believe you are saying that the script would take data from the newly created extension collection and populate data in the out-of-the-box vendor collection. 
In thinking about your solution, I believe the benefit is that any logic and reporting based on the standard collection continues to function correctly (e.g., creating an RFx from the Project will use the out-of-the-box vendor collection). 
That being said, I generally am reluctant to do a "replace" of a standard collection with an extension collection as you propose. My recommendation is that you challenge the customer on the importance of this requirement. For example, could the code be maintained on the vendor record? Why is it maintained in Projects? If it is maintained in the vendor record, could you just populate a read only collection the Projects that shows the vendor and code? Could a report be written that can be launched from within the Project to show the values? How does the customer intend to use this field? Could the display name of the vendor object be the right place for it? 
I hope these ideas are helpful. 
Regards, 
Rob
