Reconciliation of a BW and R3 data

Question

Hi All,
Please help me for this. Please provide me R/3 standard Table detail which are link with the BW standard cube. So i can do reconciliation of the data.

Hi zubs,
Data Reconciliation Scenarios
In general there are four possible data reconciliation scenarios that can be applied in a
system in order to reconcile the data between SAP source systems and SAP BI. In
addition, depending on the application area (CO, FI, SD, MM etc), some special
reconciliation scenarios are available.
1 Reconciliation DataSource
The reconciliation DataSource is a DataSource which SAP delivers as standard business
content for data reconciliation purposes. In the documentation on DataSources, a
reconciliation DataSource is mentioned that can be used for reconciliation with the
original DataSource. Alternatively the documentation describes how to design a data
reconciliation scenario for the relevant DataSource.
2 Generic DataSource with Database View or InfoSet
If no reconciliation DataSource is available in the standard business content it is
sometimes possible to create a customer-specific reconciliation DataSource from a
database view, table or InfoSet in transaction RSO2.
Since the extraction of the data reconciliation DataSource is performed remotely, it is
necessary to keep the volume of data transferred as low as possible. This process is
thus not suitable
1. If the volume of data to be extracted and transferred cannot be reduced effectively
2. If the data that the original DataSource provides is not saved in a database table
(e.g. calculated key figures).
3 Generic DataSource with Function Module
With this scenario it is possible to reproduce complex extraction logic so that the data
attained is suitable for the data reconciliation. You can also restrict the volume of data to
be transferred using data aggregation.
If the extraction logic of the original DataSource is highly complex, there is a danger that
errors can creep into the extraction logic, leading to incorrect results in the reconciliation
DataSource. Thus this scenario is only recommended for experienced developers. It is
not appropriate if no suitable data can be prepared for the data reconciliation due to
complex extraction logic in the original DataSource.
4 Direct Access to the DataSource
If none of the scenarios mentioned above are applicable, data reconciliation can be
performed using direct access to the DataSource. Dependent on the design, not all
DataSources allow direct access. This property is stored in the ‘virtcube’ field in table
roosource. If 'D' is entered in this field direct access cannot be performed. Otherwise
direct access is possible, but the runtime depends on the volume of data that must be
read and transferred from the database.
In order for direct access to function properly, the technical design of the system
(processor, memory) must enable the user to make a meaningful selection.
Since the original DataSource is applied as the reconciliation DataSource in this
scenario, any inconsistencies in the administration of the delta queue can be identified.
On the other hand, there is also the danger that some system errors may not be
identified, so this scenario should only be applied for data reconciliation purposes on a
limited basis.
Hope this helps you.
