SAP BW Tip 1 – How to identify the R/3 source for a SAP BW Extractor

To resolve problems and answer queries, it is often necessary to compare R/3 data with the data reported through BW. Just identifying the datasource for an extractor can sometimes be a challenge.

SAP Extractor

Here is some help… For Master Data, Text and Hierarchies take a look at table ‘RODCHABAS‘. This table contains entries of InfoObject/Basic Characteristics together with various entries detailing the source of the object, e.g. Function Module (field ‘MSDFNAME’) and View (field ’MSDVIEWNM’ for Master Data objects based on a view). The table also contains indicators such as Object is Time Dependant and Object has Attributes.

If it is a Transaction datasource you are investigating, take a look at the ‘ROIS’ table. This table lists all the function modules used to generate the data. Select the function module you require and enter the name into transaction SE37.
