SAP BW/4HANA is SAP’s next generation data warehouse solution. It is a new product (not a legal successor of any existing SAP Business Warehouse solution), built entirely on one of the most advanced in-memory platforms today – SAP HANA. It provides a simple set of objects that is well suited for modelling an agile and flexible layered architecture of a modern data warehouse.
Converting the system to BW/4HANA is not a simple task.
SAP provides three paths for the conversion from SAP BW to SAP BW/4HANA:
- In-place Conversion (component BW-B4H-CNV-IPL)
- Remote Conversion (component BW-B4H-CNV-RMT)
- Shell Conversion ((component BW-B4H-CNV-SHL or CA-LT-BW4)
