Identify Data Errors Early with the Extractor Checker

The extractor checker can test extracted data at the source, allowing you to find data errors/inconsistencies at an early stage.
Key Concept
The extractor checker comes packaged in Service API (SAPI), which enables you to create generic DataSources via transaction RSO2. The extractor checker has been available since very early SAP releases (both SAP_APPL including the 3.X track and BW including the 2.X track). It can be considered release-independent. It does not require the source system to be connected to the target BW system. For more information about SAPI, go to SAP Service Marketplace. You search SAP notes using the keyword “SAPI.”

By running the extractor checker in the debug mode, you can learn a lot about the underlying application. I have been in situations where I had to work with application-specific standard extractors in areas that I’m only vaguely familiar with. Running the extractor checker in the debug mode has helped me identify the base tables without a lot of effort.

I have seen generic extractors delivering no data because of faulty logic/coding. The reaction on the BW side is usually one of bewilderment and disbelief. You can avoid this by running the extractor check before executing your InfoPackages from BW. I’ll show you how to use this tool in a more effective way and explain why you might want to use it more frequently.
