Data reconciliation

BI Experts - I am using BI as my data repository to move data from R/3 to BPC. Any suggestions on what I need to look out for? Thanks.

Purpose
An important aspect in ensuring the quality of data in BI is the consistency of the data. As a data warehouse, BI integrates and transforms data and stores it so that it is made available for analysis and interpretation. The consistency of the data between the various process steps has to be ensured. Data reconciliation for DataSources allows you to ensure the consistency of data that has been loaded into BI and is available and used productively there. You use the scenarios that are described below to validate the loaded data. Data reconciliation is based on a comparison of the data loaded into BI and the application data in the source system. You can access the data in the source system directly to perform this comparison.
The term productive DataSource is used for DataSources that are used for data transfer in the productive operation of BI. The term data reconciliation DataSource is used for DataSources that are used as a reference for accessing the application data in the source directly and therefore allow you to draw comparisons to the source data.
You can use the process for transaction data. Limitations apply when you use the process for master data because, in this case, you cannot total key figures, for example.
Model
The following graphic shows the data model for reconciling application data and loaded data:
The productive DataSource uses data transfer to deliver the data that is to be validated to BI. The transformation connects the DataSource fields with the InfoObject of a DataStore object that has been created for data reconciliation, by means of a direct assignment. The data reconciliation DataSource allows a VirtualProvider direct access to the application data. In a MultiProvider, the data from the DataStore object is combined with the data that has been read directly. In a query that is defined on the basis of a MultiProvider, the loaded data can be compared with the application data in the source system.
In order to automate data reconciliation, we recommend that you define exceptions in the query that proactively signal that differences exist between the productive data in BI and the reconciliation data in the source. You can use information broadcasting to distribute the results of data reconciliation by email, for example.

Data Reconciliation Data Sources in Business Content

Can you tell me where we can find these data sources and explain me how to use them? Do we need to define infocube/ods or anything like that to load the data and use report to see the results?
Please explain me with one complete scenario.
Thanks.

It allows you to check the integrity of the loaded data by for EXAMPLE,comparing the total of a keyfigure in the data store object with the corresponding totals that the virtual providers access directly in the Source system.
Hope it will helps you.....

Data Reconciliation ... trouble shooting

Hi All Experts,
Can anyone provide me some assistance on the following plus provide me some solution.
a)Data validation btw r/3 and bw reports
b)if not possible then use se16 - but need to explain how to determine the table and the fields to be used
check if the definitions are similar between reports
check to see if there are any exclusions in the report and the data inconsistency is caused by master data loads (unassigned etc)
c)timing of the data loads - are there postings since the data is loaded into bw?
d)if the reportt definitions are the same between r/3 and bw - check the data in the cube. use listcube - explain how to use listcube.
e)determine if the error is caused by a particular package or error in update rule / transfer rule - explain how to determine this (include the package id, possible errors - full load, delta load)
include pointers on how to fix the error - asking a bw consultant to fix the error is a good idea in this case. they should not be fixing the error themselves (unless its a query issue)
Also ... data reconciliation and how to fix the errors and suggest corrections, improvements and fixes wherever possible.
TQ

a) Data validation between R/3 and BW reports can be done by getting the reports from the R/3 consultant or if u know how to get that u can do that urself. And checking them with the reports in BW ( the selections shd be the same ).
b)use se16 . For this u have to know from which tables the data is coming into BW . For example take the case or Material Master . The data comes into this Master data from the table MARA.
for this goto to the SE16 of R/3 and check the data from this table . similarly all other datasources.
c)u can check this in the delta queue of the source system.
d)Listcube is a transaction in the BW where u can check the data .
u get a screen with selections and fill the entries by defult if there are too many selection fields the system will not allow u so u have deselect all the characteristics and select few which are important or those for which u want to check the data.
e)Determining if the error is caused by paricular package or any other thing , u can find this int he RSMO transaction and select the load which failed and in the details tab u find all the information .
To see if it is caused in the update rules or TR's u have to simulate the update and switch on debugging and check the update rules and u can find out.
Data reconcilation is nothing but ur first question and how to fix the errors u will have to get the error to be fixed so if u hae any error just post the error in the forum and u will be helped by ur friends here.
Hope this helps

Data reconciliation - real example

HI,
Can any one give me a real example (for any one scenario) for data reconciliation. Please do not give me the procedure or SAP published material.
Thanks in advance

Example :
Cost Center Line Item Details Report on BI - Pick a cost center and its dollar amounts for a time period considering cost elements.
On ECC : Tcode : KSB2 - Check for the dollar amounts inputing the same selections.

Data reconciliation for Open Orders in SD

Hi,
Can any one give me a step by step approach for doing the data reconciliation for open orders in the Sales Infocube.

Hi Tanu,
Reconcilation:
Reconcilation is the process of comparing the data after it is transferred to the BW system with the source system. The procedure to do reconcilation is either you can check the data from the SE16 if the data is coming from a particular table only or if the datasource is any std datasource then the data is coming from the many tables in that scenario what I used to do ask the R/3 consultant to report on that particular selections and used to get the data in the excel sheet and then used to reconcile with the data in BW . If you are familiar with the reports of R/3 then you are good to go meaning you need not be dependant on the R/3 consultant ( its better to know which reports to run to check the data ).
I will give you a scenario to help you understand it better. Lets say BW extracts FI data from R/3. To make sure that all the records has been extracted from R/3 we can create a report in R/3 which will show the year-to-date balance of all the documents posted and we can create a BEx query on the BW cube which will also display the trial balnce. Any difference between the two balance will identify the records missing from R/3.
Similary you can model other scenarios as per your requirement. If you are extracting from 2 or more different sources from R/3 then create a multicube on top of the individual cube and produce the report. You need to also create a similar report in R/3 as well.

Data reconciliation for Open Orders

Hi,
Can any one give me the step by step approach for data reconciliation for open orders in Sales Infocube. I understand that the Open Orders which are dynamic Key figures and the data reconciliation in this case is not straight forward using "Generic View data sources" and we need to program our own generic data source with a funciton module. I would like to know if any one has dealt with this specific case and give me the proceudure to do the same.

Hi
Refer this

Data reconciliation using MDM

Hi can anyone tell me that does MDM play any role in data reconciliation across various R/3 modules.

Hi Gopesh,
maybe you want to read the thread right before this one... there i put an answer which covers your topic.
this part might be relevant to you:
Concerning 2: <b>Actually with MDM 3.0 you can consolidate any data</b> - the standard allows MD Objects like Product or Business Partner - but if you want to harmonize eg FI/CO Data you can create beforehand on MDM a MD Object type using the MD Framework - this framework allows to create any data type you like (look at the elearning sessions on the mdm page in sdn - https://www.sdn.sap.com/sdn/developerareas/mdm.sdn?node=linkDnode8 )

Data Reconciliation in BI

Hi All,
There is a requirement to do a data reconciliation within the BI system.
Requirement: PSA data from the Data source needs to be reconciled with the Data Target ( DSO or Cube).
Approach: We are planning to build a data souce on PSA using the FM based data Source and fetch that data into a new write Optimized DSO. Then a Multiprovider can be built which will conatain the new DSO and the data Target to be compared and built the Query on top of this MP and compare trhe values.
Please suggect some other strategies for achieving this.
Regards,
Mayank
Assign point is the best way of saying thanks..

Hi Mayank,
Your approach is correct for reconciliation. I would like to suggest you to include a key figure each in the DSO's for the count of records. Default it is as '1' for an entry in the DSO.
In the query, you can have the all the fields of the DSO in 'characteristics 'and the key figure defined based on the row count under key figures.
In the report for an exact match a '1' will appear for the data from both sources indicating a perferct match. A single 1 will indicate an occurence in DSO or PSA respectively.
Please ensure the structure of both the InfoProviders is exactly same.
Cheers,
VA

Data reconciliation field in rso2

Hello BW Experts,
What is the purpose of the data reconciliation button in the rso2
Suggestions appreciated.
Thanks,
BWer

You should have it in BW only, not in R/3.
The DataSource performs data reconciliation with another DataSource and should therefore not be used "productively".
For reconciliation, the data reconciliation DataSource should be used in a scenario with direct access. The data that is extracted is compared with the data in the DataSource that is to be checked.

Data reconciliation - practicl problems

Hi,
Could any one who has worked on data reconciliation tell me what are some of the practical problems that you have faced while reconciling the data.

Hi tanu,
I did data reconciliation for my previous Implementation project .If u select perfect transactions for Reconcillation U won't get any problems between R/3 to Bw .
So that u have to cocentrate perfect Transactions ,Tables to recocilate the data.
for example:
At R/3 side:
FI -AP : FBL1N
FI-AR : FBL5N
FI-GL : FS10N
Purchasing : MC$4....ect.
Thanks,

Data Reconciliation Node on SAP Source System

Hi Gurus,
I'm working on Data Reconciliation between SAP BI and SAP R3 systems. I've read on the forum that the reconciliation DataSource technology is available as of PI-BASIS 2005.1 / SAP NetWeaver 2004s. I'm using
SW Comp Release Level Highest Support Desc
PI_BASIS 2005_1_640 0017 SAPKIPYJ6H Basis Plug-In (PI_BASIS) 2005_1_640
I wonder that I cannot see the Data Reconciliation Node in the transaction RSA6 in the SAP Source System. Please throw some light on this whether I need to activate them.
Thanks & Regards,
Ash.

Hi Sunny,
Thanks for your response. Can you suggest me what should I do to get those DataSources? Are there any patches that SAP has released to overcome this problem for lower versions as the one which I'm using?
Thanks,
Ash.

Regarding Data Reconciliation

Hi,
As i understand that Data Reconciliation is used to check the consistency of the data between the source and the BI.
I have a small doubt in this regard,
When i went through the SAP Library i saw the two terms
1) Productive Datasource and
2) Datasource for data reconciliation
Are these two data sources same or not?
If i tick mark the option Data Reconciliation option in the Datasource, the same is used to transfer the data to the normal infocube and if i implement a virtual cube does the same data source is used to transfer the DS or does i need to create another
Please clear my doubt
Thanks in Advance,

Data reconciliation using OBIEE/Answers

Hi
I am new to OBIEE. I am trying to use the OBIEE and Answers for the reconciliation of the accounting entries with transaction data, However This leads to two facts one transaction lines and accounting lines. I can make the transaction lines also dimension. But in such case can I compare the transaction amounts with accounting amounts something like
Transaction Total – Accounting total – difference .
Thanks a lot in advance.

Hi
Still I am not ready with complete data model. However I Can explain. we have the customer, transaction types, date , Currency as dimensions. These dimensions are linked to the transaction Fact where we have the transaction amount like Invoice amount for each Transactions, open balance for each TXtransaction. We have another child table to the transaction table called accounting distribution table. Now i can build two differnt star one for transaction as fact and another one as Accounting flex. In such a case in we join both fact in presentationlayer to get the transaction amount and accounting amount compared. Also another question is can we have the both facts in the same schema. Or any other approach?
Thanks a lot in advance

Data Reconciliation between BI and R/3 systems

Hi Gurus,
I want to know how to reconciliation the data between BI and R/3 systems.
is there any easy mentods to reconcile the data.i have also gone through the HOW TO GUIDE document, that document dosen't help me out.
Regards
Sreenivas.Y

1) Either we can reconcile using standard R3 tables eg VBAK , VBAP for sales .
2) You can go for automatic reconcillation where you will have to create a reconcillation data source and extract it to BW using virtual cube (Virtual cube would extract real time data from R3).
Include original cube and this virtual cube in a multiprovider .
Make a report taking keyfigures from both the infoproviders and add a column for difference .If there is 0 difference it means BW data matches with R3 .
