Transformations
Transformations in SAP BW/BW4HANA define how data is mapped, converted, and enriched as it moves between InfoProviders, DataStore Objects, and InfoSources during the ETL process. This topic covers rule types, transformation design, routine-based logic, troubleshooting data load issues, and how transformation behavior differs across BW on ECC, BW/4HANA, and embedded analytics scenarios.

Lessons in this topic
- Designing and Troubleshooting Transformation Rule Groups and RoutinesCovers how to design multiple rule groups for different source scenarios, use start/expert/end routines effectively, and systematically troubleshoot transformation-related load failures.
- Understanding BW Transformations: Purpose and Core ConceptsIntroduces what a BW transformation is, why it exists in the data flow, and the basic rule types used to map and convert fields between source and target objects.
- Using Start, End, and Expert Routines for Custom Transformation LogicLearn how to implement ABAP-based start routines, end routines, and expert routines in BW transformations to handle logic that field-level rules cannot express, including package-level filtering, lookups, and record consolidation.
