Field Specific Change Log

Hi All,
Is it possible to only log the changes for specific fields of a table? My guess is this is not possible but it is suggested not to log data changes due to performance issues. If we were to limit the tables to specific fields, perhaps we can limit the affect on performance.
Also, how big of a hit on performance can we expect if we only add logging for one additional table?
Thanks. Points will be awarded for helpful responses.

Thanks, Anji, but I was wondering if it was possible to set specific fields. So let's say I have table ADRC and I only want to see changes to field NAME1. Can I set only this field to be logged instead of the entire table?

E-Recruitment - Requisition - Infotype Field Level Change Log

Hi Experts,
We are implementing SAP E-Recruitment, and would like to know how to capture the changes made in Requisition at infotype field level.
For example: If a support team member is added/delete in the Requisition (Tab - Support Team), then these changes (NEW/DELETE) at the infotype field level are required.
I have tried to maintain the infotype and the required fields in V_T582A, V_T585A, V_T585B and V_T585C. But didnt get any result when I executed the report RPUAUD00. Is there any additional configuration required for this?
Please adivse.
Thanks and Regards,
Dinakaran R

Hi,
You can just to that with the infotype table log. Support team is stored in table HRP5131.

Filled fields become blank in DSO change log

Hi experts,
I find an unusual behavior in DSO activation.
For some records for which I find in PSA, new data table (and in debug also!!!) correct data, when the request is activated I find in change log table all characteristic fields empty; the key fields and key figure fields are ok and correct in all tables.
It happen randomly for some orders and for a few requests.
It happen when I have one storno record, for example:
PSA (order, item, customer, material, storno, quantity)
10000, 10, AAA, YYY, , 25
10000, 10, AAA, YYY, X, -25
DEBUG (order, item, customer, material, storno, quantity)
10000, 10, AAA, YYY, , 25
10000, 10, AAA, YYY, X, -25
CHANGE LOG (order, item, customer, material, storno, quantity)
10000, 10, AAA, YYY, , 25
10000, 10, , , X, -25
ACTIVE DATA (order, item, customer, material, storno, quantity)
10000, 10, AAA, YYY, 25
In some other cases:
ACTIVE DATA (order, item, customer, material, storno, quantity)
10000, 10, , , -25
Have you some ideas? It is very strange.
We are on a 7.0 BW system, but with 3.5 data flow (update rule).
Thanks in advance.

Vito,
This happens some times...
1. Did you transport any change to this DSO where characteristics were added and are these the ones that are blank...
When this happens - see if you can clear the change log ( if this is an option ) and then reactivate the cube.
Also there is a program to regenerate the activation program, I am not able to locate this - but then usually reactivating the ODS will usually clear this issue because it regenerates the activation program.

Change log for Z field while doing a direct update

Hi ,
I have a Z field added to the EKKO table and the change log is activated . Any change to the Z field from the transaction ME52N is updated in the CDHDR , CDPOS tables .
The issue I have is now i have a requirement to update this Z field through a program . I could update this field but the change doesnt get into the change log . But the change done from the program appears in the front end screen i.e ME53N.
Please help me on this.
Regards,
Hari.

Hi Hari hara Kumar,
As far as my thinking, there is only one solution for this, do a recording/BDC(I know that Enjoy transaction BDCs are not successfull but as you have only 1 field to update,you can have a try) to update the Customer fields or Using the BAPI you can update the same to get change records, but it will be a long procedure to add Z field in the BAPI structures and then do that required coding, better is to have a try a with the BDC. I will never ever do a direct DB table update using a Z program for Standard tables.
Thanks & Regards,
Faheem.

Hi All,
I need the change log for custom fields added in BP transaction codes.
Basically, for tracking the changes of master data in CDHDR and CDPOS tables we will enable the checkbox of dataelement related to custom field.

Please let us know if iam missing any other thing?

Change log of field USERTYP

Hi all, is there any way how to find history of changes of the above mentioned field? I am not able to find it via SU01->Change documents for users.

Hi Jaroslav
Sorry for late reply
Standard table USR06 change log is not there as there is no particular object maintained for recording log not allowed as technical settings. Below are some selected of US category for which you can search change log.
USLA04
USR21
USRACL
USREFUS
USOBT
USOBX
USOBT_C
USOBX_C
USMD120C
USMD120C
USR41

How do we control what fields you need in the change log?

Gurus,
Some time ago in an unrelated problem solving activity I came across the configuration screens that controlled what (and if) you could log when changed.
I can not find the place now.
There should be a place in SPRO which allows me to configure that I do not want log of the change in sales orders. It also allows me to choose which fields within the sales orders should be logged. So I could choose (say) to have the logging of quantity changes to be turned off.
Was I dreaming? ... Can someone point me in the right direction?
Thank you all for contributing
Regards
Raju

I have a direction now:
1) Check in the SE11 to ensure that the field that I need the change log for is marked "Change Document" in the Data Element of the field.
2) Check the document object VERKBELEG (Sales Document) to ensure that the table is included in the configuration. Transaction SCDO.
I will experiment with this to find out if this can be done.
Regards
Raju

Customer Master email field - change log not appearing

Thanks!

Sorry.. not an issue

Change log data is NOT captured for PO screen exit fields

Hi,
We created a new tab at item level for PO Screen(ME21N) for the purpose of STOs(Document Type UB) & created 3 New fields in that new tab through Screen Exit( SAPMM06E, SAPLXM06 0111 ).
When we are entering data in those 3 new fields while creating new STOs, those data are captured in EKPO table.
When we are changing the OLD STOs for those 3 new fileds, data is modifying in EKPO table. But changes are NOT inserted in CDHDR and CDPOS table for those 3 new fields.
<b>Please help us to track the changes in those 3 new field data changes for old STOs.</b>
Please let me know if you need any further clarification regarding this.
Thanks & Regards,
Mani.

Sales Orders Change Log question

Hi All,
I am currently working on a project that involves querying SAP Database to get custom reports via web browser, I've made a lot of advances and most of the site is ready but I'm missing just one item that I hope you could help me.
Thing is I am working with the Sales Order change log and the problem comes one a user deletes a row. If I go to the change log inside SAP and see the differences a new record will be shown saying that row X was deleted and
if I go to the database (ADOC and ADO1 tables) I don't have a way to see wich row was deleted.
My way of doing this is to check for the number of rows on the current state of the sales order and check the same on the previous instance of the SO and see if a line was deleted. Then I would have to check row by row between instances what rows are there and what row is missing and store that info. I think this kind of approach will definitively kill the server.
I was wondering if some one can give me a hint about how to approach this problem. Does any body know how SAP works on this area?
I'm working with SAP2005A and SQL Server 2005 Standard Edition.
Any help is greatly appreciated.
Thanks!

Hola Alejandro,
Thanks for your answer, as I see it I'm doing exactly what you proposed but the problem comes with the following scenarios:
a.- If I post a new SO with two lines I will have on the ADO1 table two records with the values 0 and 1 for each line respectively but if I delete the item on LineNum = 1 and then I add a new item, this last item will be also created with LineNum value = 1. This is not a complicated thing to do but the problem comes when the user is used to work with SOs with several items at detail level and is used to add and erase lines once in a while and as I see it it's very difficult for me to track those specific changes. There's also the fact that on the Log table a new instance is created every time the user hits the update button regardless if a modification was actually made or not. I mean I would know that a line was deleted or added but I would have to start comparing each field on each line of a sales order with it's previous instance to check what was actually added/deleted and I'm afraid that this may affect the server performance. I know that SAP does this without affecting to much the system resources and that is what I'm trying to find.
I forgot the other scenario I was considering he he I will post again as soon as I remember it but I hope I'm explaining this ok (I'm not very good at explaining...) If not let me know and I'll try to explain again.
I'm also working on trying to get another approach to see what comes up...
Thanks for checking this thread, your answers are helpful.

Change logs for Z table.

Hi All,
I am trying to fetch the old value and new value for the z table field.Change log is activated for the Z table. but i dont know how to fetch the change logs.
SCU3 is the standard transaction to see the change logs for all the tables.
Is there any table where the change logs values are maintained?
Does anyone know how to get the change log value?
Thanks in advance.
Regards,
Amruta.

Hello,
If for a specific set of tables no change documents are triggered by SAP you can always setup your own Change Document Object with transaction SCDO.
Of course you need to be careful with this transactions (how big is the table data, how many changes, etc...).
Table logging is something else, they are stored in table DBTABLOG and can be analysed via SCU3.
For table logging you need extra system parameters to be set, they are explained in SAP Note:
Note 1916 - Logging table changes in R/3
Pay attention with table logging because a lot of tables are logged in DBTABLOG once you activate the parameter, this can have a major impact on performance.
To have an idea what other tables will be logged, check tcode SE16 on table DD09L and put an 'X' in field PROTOKOLL, result will be thousands of tables.
In your specific scenario I think it is best you go for the change documents with SCDO.

PM Order Change logging / OIOE

Hello,
Does anybody know if it is possible to enable change logging for PM orders for the text description field? (KTEXT). I understand that overall, logging is governed by t-code OIOE, however it appears that only certain elements are logged from what I have found. Perhaps I am looking in the wrong place, or perhaps this level of logging is not possible?
Basically, I want to be able to look at a specific order number, and be able to see a log of all changes made to the order including everything from status changes to the data that was changed. Is this possible?
From within the order itself (IW33) looking at the 'Changes' as well as 'Action Log' don't quite tell the entire story.
Anybody have any ideas?
Thanks!

Fricis,
Change document is enabled for the KTEXT field on the order header.Not sure why you arent able to see it on the chnage document log.
OIOE transaction does control capturing of changes for certain elements. The field that these elements contain is governed by the change document structures associated to the objects (Transaction :SCDO. ex: ORDER is the Change document object for PM order and Networks). The data element of the fields associated to the structure inturn control whether changes should be captured or not.For order header short text KTEXT, the data element associated to it AUFTEXTwhich does have the change document activated. You could switch on change document(It will result in a modification ) for fields which arent active for logging changes on tables which are already in the change documnet object.
Custom report is probably your only solution to access all the change documents for the order (Order header, operation, header status, operation status, material status etc) in a single screen.You could probably trying copying the action log logic and expanding on the same for everything you need.
Hope it helps.

Specific changes are left undetected when using proxy indirection

Hello!
Recently, the following issue have been identified:
ObjectReferenceMapping together with ProxyIndirectionPolicy and *UnitOfWorkValueHolder fails to identify specific changes - setting a reference to 'null' when the attribute's value was not instantiated previously.
Detailed description:
Consider we have 2 objects: A and B, and A has OneToOneMapping to B and uses ProxyIndirection.
In initial moment we have A1 that references B1 in DB.
Then we register A1 for modification. What we have in memory in UnitOfWork? Something like the following:
A1(Clone) with attribute for B reference uninstantiated;
A1(Backup) with <null> reference for B, as the attribute is expected to be retrieved when we access B from A1(Clone).
Then we set reference in A1(Clone) for B to <null>.
This change then will not be identified during commit phase, because of the result of getAttributeValueFromObject both for B reference in A1(Clone) and A1(Backup) is <null>. This part is clearly visible from the ObjectReferenceMapping.compareForChange method code:
if ( !owner.isNew() ) {
backUpAttribute = getAttributeValueFromObject(backUp);
if ( (backUpAttribute == null) && (cloneAttribute == null) ) {
return null;
Accessing the B field in A1(Clone) fixes the problem, because in this case backUpAttribute value is initialized through *UnitOfWorkValueHolder.
So it seems the part should be reworked to handle such cases, it seems reasonable that fields in backup clones that are using proxy indirection should be initialized even if not accessed to contain all required information to allow correct comparision in such cases.
Can somebody from TopLink team comment this?
Thanks,
Sergey

This does appear to be an issue. I will log this problem internally, you may want to follow it up with support.
A work around is to instantiate the proxy in your set methods.
i.e.
public void setAddress(Address newAddress) {
if (this.address != null) {
this.address.hashCode();
this.address = newAddress;
}
