Change documents with persistent class

Hi,
I have created a persistent class and want to use a set-method to change data in the mapped table - nothing special.
But: Does anybody know if there's a possibility to write change documents for the changed field without calling FMs like CHANGEDOCUMENT_SINGLE_CASE?
There would be the event if_os_state~changed but unfortunately no information about the changed field itself is available in this event. Is it possible to redefine events?
Thanks a lot for each answer!
Best regards
Jörg

Hi Narin,
thanks for your answer!
The first point is plain to me (although I don't really feel happy about this ) but I have problems understanding your second point because I don't really know what "Business object events" are... I'll try a different phrasing, maybe this is better:
My persistent class inherits the event if_os_state~changed. Can I redefine this event in my class so that I can add an additional parameter where I can put the information about the changed attribute?

Enhance ZMMJ or Normal Change Document with Custom User

Hi there,
I am wondering if it is possible to add a specific field into a change document.
We have a requirement whereby 2 different testers need to be added to a change. The first tester will perform testing of Development in DEV (as per our custom workflow) and then the second tester will perform the normal testing in QA.
Now these two testers might not necessarily be the same person or have the same authorization.
So, my question is that when you are assigning team members to the change (Developer, Tester, Change Manager, IT Operator), is there an option to add another user field here, such as Dev Tester?
Thank you.

Hi Bradley,
SAP Note 1728284 has a PDF Attachment with a detailed description what needs to be done. Please follow this description to adapt your configuration.

Change documents for item class 015

Dear Experts,
Kindly guide me how to get change documents for notification item class 015.
THANKS & REGARDS

Hi,
All the changes in the documents will be located in CDPOS and where as the status change documents are located in JCDS.
What we have to do is to enter the correct object number.
i think by this you get the issue resolved.

Change Documents for Material Class

Hi,
I activated the change logging for a specific Material Class. However, when I check the change log, there is a material class which will show the characteristic change in the following format. For example I modified characteristic ABCDEF from 1 to 2. The log will show the following:
Document Number 099999
ABCDEF - 1       Deleted
ABCDEF - 2       Created
There are other class types/characterisitcs whose change logging is also activated but the change log will only show the "Created" part. The old value (before change) is not shown.
Document Number 088888
ABCDEF - 2       Created
How do I turn on the logging in such a way that the deleted value (old value) will always be shown in the log ?
Thanks

We have the same issue just come up last night.   A test on one class last week yielded the 2 record change history model (old value deleted, new value created). Applying the same change to a different material class, we get only the single record model - no help or oss notes seem to mention that there are two different change history models in SAP.
CHECK THIS -- check your single record change log in table CDPOS ... you may have values in both value_old and value_new fields there. The 2 record model stores value_old on the "deleted" record and value_new field value on the "created" record.
That still does not answer why there are two models and how one controls which model is implemented for change history on a class/characteristic ... but it sheds just a little more light on it.

Activating 'change documents' for notification item class 015

Dear Experts,
Kindly help me in activating 'change documents' for notification item class 015.
Thanks and Regards,
R N Sabat

Hi R N Sabat
The creation of change documents for the classification has to be
activated for every class type. Go please to the customization of the
appropriate class type:
Cross-Application Components
-> Classification System
-> Classes
-> Maintain Object Types and Class Types
You will find there a flag to activate change documents.
As a precondition you'll have to activate the flag 'Multiple objects
allowed' before. If you already have classified objects
for this class type these classifications has to be converted before.
For the conversion of already existing classifications use please report
RCCLUKA2. It processes the conversion and sets the flag 'Multiple
objects allowed'. Regard please the documentation of report RCCLUKA2.
Thereafter you'll be able to activate change documents for this class
type.
Please check the 2 notes :

Updating linked fields in a persistent class

Hi all,
If a field of a persistent class is updated, what is the best way to update a related field?
Scenario:
A persistent class with public GET/SET access to a table field STUFF, and public GET access to a field CATEGORY.
Whenever SET_STUFF is called from the outside, the class should also re-evaluate and update CATEGORY.
The easiest is to modify the SET_STUFF method to determine the new category and update it if necessary. However GET/SET methods are always overwritten whenever the class is regenerated, which happens all too easily. Can this be done a bit more elegantly?
Most modifications can be done by redefinitions of the agent class and do not get overwritten each time the class it regenerated. e.g. I have done something similar by redefining the DB access methods to update various fields, but for my current requirement the update needs to be immediate, not during save.
Any input appreciated,
MIke

Hi Naimesh,

> Updating the field CATEGORY immediatly would lead to some problems while working with Persistent class because of the COMMIT WORK. As soon as COMMIT WORK after the CATEGORY's "save" hits, all pending save request would execute and may update some fields which you don't want to update at that point of time.
No COMMITs should be performed, that's part of what I'm trying to accomplish. STUFF may change several times during the lifetime of the process and CATEGORY must change with it. When the application finally does a COMMIT WORK then both are written to the DB. (In fact my real scenario involves both transient and persistent instances and multiple callers).
My objectives are to have a readonly attribute in the persistent class that changes in response to other fields changing. It should behave as though the app is calling a SET_STUFF and a SET_CATEGORY, but the persistent class must retain control of the CATEGORY field as several applications can modify STUFF.
My current workaround is an UPDATE_CATEGORY method that must be implemented by each caller, so it works. Layering another class above it an option but is a bit of overkill which also makes it a workaround.
I have found that EXT_HANDLER_WRITE_ACCESS seems to provide something, but the comments in there seem to indicate I shouldn't modify the object info. Unfortunately I have run out of time to experiment this week so the workaround will have to stay for now, but I'd still be interested in a more elegant solution.
Thanks for the input,
MIke

Can't display archive change documents for agreement (COND_B)

Hello,
I want to display archive change document for object class : COND_B (agreement) via transaction MEB3:
The archive works fine, and I can found the archive change documents form SARA.
(Archive Objetc = CHANGEDOCU
Archive info structure = SAP_CHANGEDOCU2 (is active))
But the display from the application transaction : MEB3 doesn't work.
In the DEBUG:
the Function module is called automatiquely: COND_B_DISPLAY_DOCUMENT
THEN SUBMIT RSSCD100
THEN The function module is called with the no parameter READ_CHANGEDOCU (ie with space value)
THEN the program reads only from DB
Question : HOW I oblige the program to read from the archive (READ_CHANGEDOCU = 'X') ?
I checked these SAP notes 1050935,1299903, 1308024, 1128954, 1050335
but no results.
May be I forgot some customizing ( SARA,, AOBJ )?
Thanks for your help.

Hi,
As I understand, the change documents archived using the CHANGEDOCU archiving object are no longer available using the application object.
Refer to Notes 1257133 and 140255 where they mention the above point.
If you want to read change documents along with the application, then you must first archive the change documents along with the application.
In your case, for agreements, you should use object SD_AGREEM so that the change documents also gets archived along with the agreements. Refer to note 761281 to check whether the archiving class CHANGEDOCU is already defined along with object SD_AGREEM in your system.
Hope this helps,
Naveen

Regarding a Change Document Function Module ----- VERY VERY Urgent

I am using a Change Document Function module "CHANGEDOCUMENT_READ". It is taking a long time.
I am using the parameters:
Start date is the first date of the current month
Enddate as last date of the current month
Object class as 'MATERIAL'
Table Name as 'MBEW'

Hi ,
When you want to read the change documents, please follow the below process.
1. Read the change documents headers with function modules
call function 'CHANGEDOCUMENT_READ_HEADERS'
       exporting
            date_of_change             = cdhdr-udate
            objectclass                = cdhdr-objectclas
            objectid                   = cdhdr-objectid
            time_of_change             = '000000'
            username                   = cdhdr-username
       tables
            i_cdhdr                    = gt_cdhdr
       exceptions
            no_position_found          = 1
            wrong_access_to_archive    = 2
            time_zone_conversion_error = 3
            others                     = 4.
2. From above step you will get data of change documents very quickly into Itab (gt_cdhdr)
3. Read the details on change documents with functiion module by using Itab in loop for each document.
loop at gt_cdhdr.
    call function 'CHANGEDOCUMENT_READ_POSITIONS'
         exporting
              changenumber            = gt_cdhdr-changenr
         importing
              header                  = cdhdr
         tables
              editpos                 = gt_cdshw
         exceptions
              no_position_found       = 1
              wrong_access_to_archive = 2
              others                  = 3.
Above is the best way to read the change documents.
Rewards please if above info is useful.
Thanks.

List all active change documents

Is there a way to list all ACTIVE change documents? In other words - I only want ot know which change documents are being used in the system...
Thanks

Thanks Anji - Seems there is no place to show if a change document is active, but I was being silly since if a change document is not active or being used, it will not appear in CDHDR / CDPOS!
A useful pool table is TCDOB - It lists all change documents with properties like which tables they monitor etc...

ABAP OO Class and Change Documents

I have created a class based on the IF_WORKFLOW interface. I created a couple of events. I created a workflow task assigned to a custom method of the class. I setup the Material Change Document to trigger the class event when there is a change. The workflow task does trigger when I change a material, but I don't know how to pass the key of the Change Document (matnr) to the workflow task/method using the ABAP OO Class interface. Any help?
Thanks,
Kenneth

Thanks for the reply Florin. Yes, I have seen Joclyn Dart's Whitepaper and blogs. They are very helpful, but I haven't seen much information within them about Change Documents. I tried your suggestions, but the material key is still not being filled when I trigger the change document and workflow task using tcode MM02.
Here is what I have done:
Created an Attribute 'Material' type mara-matnr and checked 'Key Attribute'.
Created an Attribute M_POR type SIBFLPOR.
Here are the methods:
Constructor with parameter 'Material' *
METHOD constructor.
me->m_por-catid = 'CL'.
me->m_por-typeid = 'ZMM_WF_MATTEC'.
me->m_por-instid = me->material.
ENDMETHOD.
Find_by_lpor with parameters LPOR and RESULT (default params) *
METHOD bi_persistent~find_by_lpor.
DATA: p_material TYPE matnr.
MOVE lpor-instid TO p_material.
TRY.
      CREATE OBJECT result
        TYPE
          zmm_wf_mattec
        EXPORTING
          material      = p_material.
    CATCH cx_bo_error .
      EXIT.
ENDTRY.

Problems with generating persistent classes

I've been following the tutorial for generating persistent classes from a
DB. I'm not having much luck:
First, with rd-schemagen, how do you tell it to only work on a specific
schema? I run "rd-schemagen -file schema.xml NBS_ODS_101", but it still
generates the schema file for all schemas in the DB. Is there a usage
option for the tool (I haven't been able to find it yet)?
Second, I have the following tables in my DB: ACT, ACT_ID, ENTITY,
ENTITY_ID. When rd-reversemappingtool runs on these tables, it creates an
ID class for ACT (ActId) which conflicts with the class generated for
ACT_ID (ActId). Since renaming the tables is not an option and I really
don't want to have to rename classes and change the mapping file every
time I regenerate, what is a solution for this problem?
Third, if I do the latter above so I can run the importtool and then I
run "rd-importtool test\test.mapping", it runs successfully for a bit
while spitting out information until I get this:

good way to tell you to work around it for now, unfortunately.I renamed the ID classes to ActOid and EntityOid and changed the .jdo file
to reflect that. Do you see any problems with this strategy?
