How the master data delta works

hi, experts
i want to know how the master data delta (ale pointer) works? what the principle is? for example, the 0asset_attr datasource has 20 fields, any of the 20 fields changes can triger the delta? if i enhance 3 fields to the asset master data, does the 3 fields change can trigger delta?

Application Link Enabling (ALE) change pointers are configured and used to be able to trigger processing of an outbound process, such as data extraction, and determine only those Master Data records that have changed. This is all done without the need for a program being required to determine deltas.
SAP delivered program, RBDMIDOC runs periodically and deterlines if change pointers have been updated for specific message types. New or modified Master Data records are automatically initiated via ALE. RBDMIDOC references the correct IDoc program for any given type via TBDME (the TBDME table also cross-references message types with the ALE change pointer table) so that the data goes where it should and is processed accordingly. Tcode BD60 is the interface in SAP for maintaining the TBDME table.
When a change is made to the standard content Master Data record, the delta will be identified. Any columns that have been enhanced to the Master Data will not be identified as a delta because enhancements are a post-extraction process and only get updated after the standard content structure has been populated.

How does Master Data delta works.

Can any body please explain me what is data flow in master data delta.Are the ale change pointers utilised , if yes how..And is delta queue used in master data delta.

Amit,
As you may be aware of this, ALE Change pointers are used to minimize the no of records to be sent to the extracting systemextractos. in other words the master data delta is been handled this way. It is better that you read the following that should be giving you some idea.

How the master data of multi language is shared in the info cubes

hi frindz,
how the master data of multi language is shared in the info cubes
bye bye
venkata ramana reddy.G

Hi Ventak,
In the infocube you have the key. Then you have a text master data table that has as key (for the table) the key of the value (the one in the cube) and the language, and the text in that language as another field (short, med, long).
Hope this helps.

Generic and Master data delta.

HI,
Will you please give me the solution for 'The differenet delats we have in generic delta,what actually is a numeric pointer.. how does it pick delat..is it something like it picks a record which has changes in it or it it each neew record..
if suppose we have 1 to 10 customers, will numeric pointer pick every new customer like (11, 12 , 13) as deltas or changes in 1 to 10 customers itself..
And Regarding master data deltas,how will the master data pick the deltas, is it every new record as customer mentioned above will be picked or something other..
the basic thing i want to know is, will it pick any changes in attributes as delta also.. if suppose we have a customer 001 with an attribute as 0ACCNT_GRP, if in any case if this 0ACCNT_GRP has change.. will it even pick this as an delata or not...
i would appreciate your response..
Thanks & Regards,
Shashikanth.

Hi Shashi,
Well....I could give some points on the master data delta..Its achieved by the ALE change pointers mechanism.
There are some tables responsible for storing the changes...CDHDR and CDPOS are good candidates for this.
Hope this helps..

Is there settng source system level for master data delta loading perfo

Hi Viwers,
Good Morning,
I am loading data from the source to target level for Master data it is taking too much time,I would like to know the how to increase the master data delta loading performance.
I would like to know the source system level is there any setting requited & target system level also.
Please give your inputs..........
Thanks & Regards,
Venkat Vanarasi.

Venkat -
Are u deleting the indexes of data target before delta loading ? If not,delete the indexes of data target before delta loading and recreate them after delta loading is done.This procedure increase load performance.You can perform whole procedure in process chain.

Message Type inconsistent for Master Data Deltas

Hi All,
I have a question regarding the message types for the master data deltas. What I noticed on our server was that the message types (TCODE: BD52) is different for different severs for the same master data deltas (mostly they would begin with RS. If you do a wild card search RS*, you would find them for the different master data delta enabled extractors). Is this standard or is there something that we can do about it? I only ask because we modified the message types for one of the extractors to <u>create</u> a delta for the enhanced field on our extractor. This was done to create a delta when the enhanced field changes when nothing else changes on our standard extractor.
Please advise. Also let me know if you want me to clarify something above.
Regards,
Ashmith Roy

RSnnnn message type is created/assigned(in the source system) first time you initialize the delta for the master data. Hence it is normal to have different no assigned to different master data depending on when the particular master data was init (on that system).
When you say you enhanced the message type, what did you do?

REPEAT DELTA WILL WORK FOR MASTER DATA DELTA LOADS

Hi Guru's,
REPEAT DELTA WILL WORK FOR MASTER DATA DELTA LOADS?
AS I AM NEW TO SAP-BI CAN ANY ONE GIVE THE DETAIL EXPLANATION ON IT.
IT WILL BE GREAT AND HELPFULL.
Thanks and Regards,
CM

Hi CM,
yes you can perform the repeat delta even for the master data if the datasource which was supplying the data was delta capable.
You can do the repeat delta only in case if your previous request was erroneous and dont forget to make the request red in the status,so that system will treat like you are requesting the failed request once again where in case you will miss the previous request, i,e erroneous request if you dont make the request red.
when you make the request red manually in the status,the pointer will move to the previous request once again in the delta queue and there will be no chance of missing the delta records.
This process was same for both transaction as well as master data.

Open hub Services - How to extract the master data related to a object ?

Hi Gurus,
I am implementing OpenHub services for our project, it's on BW 3.5, I have the list of required fields with which I am creating an InfoSpoke. Now I am stuck in some the info objects which are having master data associated with it.
Example : Business partner(BP) data, when I map the 0BP infobjects in infospoke it's extracting the BP ID (ex: CT065316,CT068638 etc) in flat file but I want the BP name, address & telephone number as well, which are coming from master data table. But I am able to map only 0BP infobjects as a part of ODS/Cube.
Can any one tell me how to get the master data extracted in the flat file with associated info object???
Answers will be highly appreciated.
Regards,
Kironmoy Banerjee
Edited by: Kironmoy Banerjee on Oct 1, 2009 3:34 PM

Hi Kironmay
Please follow the below mentioned procedure to create a transformation. This is applicable for BW 3.5 as well.
- Enter your infospoke in the edit mode.
- On the Transformation tab set the indicator for the Infospoke with Transformation with BADI so that the infospoke is activated.
- This will take you to the Addin implementation/BADI builder.
- Enter the short text/description for the implementation. The implementation name is always the same as the technical name of the infospoke
- The implementation of the BADI is always filter dependant.
- In the properties tab of the infospoke enter your infospoke under the Filter specifications.
If you do not specify an InfoSpoke under Filter Specifications, then this implementation is valid for all InfoSpokes. This means that this is called up for all InfoSpokes during the extraction.
- Activate your class
- From your interface tab page, double click on the Transofrm Method and you will arrive in the class builder page
- Here you can enter the code
- To do a look up of the master data you have to write a code similar to the one I've given below. This is just an example for looking up material master.
IF FLT_VAL = 'Your infospoke'.
T_DATA_IN[] = I_T_DATA_IN[].
Select zstd_cost from /bi0/pmaterial into table T_return
For all entries in T_DATA_IN
WHERE material = T_DATA_IN-material.
...Continue with your code.
Append output from T_return to your output E_T_DATA_OUT
- Activate your method. Return to the BAdI builder. Return to your InfoSpoke.
I hope this helps.
Thanks.

How to fill the master data in ecc

Hi,
0product_attr having zero records i ecc,how to fill the master data in ecc can you pls provide me the setps?
Regrads,
devi.

Hi Devi,
Loading data is ECC is not the part of BI Activities. Contact your functional consultant to load data.
BDC and LSMW both are used for loading data into SAP system.
Or ask even directly they can create in ECC. If it is for your testing purpose, it is better to ask them to create master in source system .
Thanks

How to find all the Master data extract structures and Extractors

I intend to create Master data dimensions closely similar to SAP BI in a 3rd party system. I would like to use SAP's standard extractors for populating the master data structures in SAP BI and then use a proprietary technology to create similar structures in a 3rd party database.
Question: How to get a complete list of all Master data extract structures and corresponding extractors?
Example: In ECC if I do SE80 and give 'Package' and 'MDX' and then press the 'display' spectacles, I get a list of structures and views under "dictionary objects" covering Material, Customer, Vendor, Plant Texts and attributes.
How do I get the remainder of the Master data extract structures viz. Purchase Info Records, Address, Org Unit etc?
Regards
Sasanka

Hi,
try the table ROOSOURCE and search the data source with string in astrick attr for master data and for text with text
This will give you the list of all the master data source in the system and it contains a column which tells about the extract structure and function module used by each.
Thanks

How Consolidated Master Data Gets Linked to the Transactional Data?

Hi,
Suppose we have three legacy systems holding customer master data. We fetch the data from these three systems into MDM and consolidate the records. Let's say there were three customer master records:
CUST123, John James, 123 Elm Street
CT00123, James, John, 123 Elm St.
0000123, John James, 123 Elm Street.
We merge them in MDM and create one record
NEWCUST123, James, John, 123 Elm Street
Question is: How the transactional data from the three legacy system will be mapped to this new customer master record? How the purchase orders will know that CUST123 is now NEWCUST123 ? When this mapping happens in a project and who does that?
Regards,
-T
Edited by: mdm3north on Jul 21, 2011 2:30 AM

HI,
I agree with Anil on that,it is the same reason for which few projects have key mapping repository in place,which holds the key field mapping information telling them that this Customer number means this in the Legacy system.
Well manual intervention is required as PR/PO which is active should be closed before such an activity.
Thanks,
Ravi

How to Lock the master data. R/3 Conflict ESS

Dear Gurus,
Please guide me how to lock the master data for a nos of days(say 7 days).
Recently we had encountered an issue, related to ESS. While Uploading the Time data through t-code: PT60, our core team encountered a problem, that such and such employee number is locked.
While checking, they identified it, system shown error against those employees, who are accessing their ESS. We check and came to know they are accessing the master data by changing their personal record i.e. address.
Do we have any other provision to lock the master data without setting the control record to release for payroll.
Please help .

Create a custom transaction involving a custom views of table T7XSSSERSRV with the following field for each service
"V_T7XSSSERSRV-ISDISABLED"
when HR wants to lock it, the will enter this table and check this field.
this will disable the servcies in the front end.
Once the 7 days are over, HR will uncheck this field. this will re-enable the services in the froint end.
Hope this helps.

How to regularly update the Master data/Text/ Hierarchy for BW DEV?- Urgent

Hi Experts,
Can anyone help me to understand how to update the Master data/Text/ Hierarchy regularly for BW DEV.
Since all the new query developments are taking place in DEV, users are not finding the latest Masterdata/ Texts /Hierarchy in the DEV system.
I have searched in SDN and got a document "HOW TO DOWNLOAD A HIERARCHY TO A FLAT FILE". However, is there any other way to upload the master data automatically on periodical basis.
Please help urgently.
Advance Thanks,
BW USA

If you want to extract master data from PRD in order to load in DEV, i suggest to do this (its a tricky thing):
For example, you want to download 0EMPLOYEE
1-In PRD, transaction RSD1
2-Enter 0EMPLOYEE
3-Copy the Master table for 0EMPLOYEE (/BI0/MEMPLOYEE)
4-transaction SE16
5-Enter the table name /BI0/MEMPLOYEE
6-in the selection screen, go to "Options" Menu and select "User parameters", and now select "Standard List SE16"
7-Execute
8-Now its show's up the 0employee data, go to "System" menu - List - Save - Local File
9-After you have the flat file, only rest create Infopackae in DEV Env. and load it from the flat file.
Asigns points if useful.

How to find the size of the master data objects in the BW system?

Hi,
We would like to understand the size of the master data tables overall for a specific source system (Logical name is Ex.ABCD, which supplies all master data to BW). Can you please advise the procedure to find out this?
Is there any table that will allows to see all the master data objects related to specific sources system so that we can find out that table size? Thanks.
For example, we have many Texts, Hier & Attributes.
0COUNTRY_TEXT
0REGION_TEXT
0PERSON_ATTR
0MATERIAL_LPRH_HIER
Advance Thanks.
Edited by: BW USA on Feb 2, 2010 10:52 AM

Hi,
You can find out all the master data tales used in the BW system by
Tcode : SE11
Enter as /BIC/P* for master data tables and press F4 which gives list of master data tables currently used in BW system.
Similarly for Texts /BIC/T* and press F4
Similarly for Hierarchies /BIC/H-* press F4
and can know the size of the all tables.
Thanks,
Gopal
