Custom transformations in SAP BW (as of SAP BW 7.4) are implemented using ABAP routines – Start, End or Expert – which are executed on the ABAP Application server. During execution of ABAP based transformation, data is retrieved from database to the application server for processing and transformed data is written back into the database. Data transfer thus happens twice during ABAP runtime, once from database to application server and again back to the database. This, coupled with row-by-row processing of field-based calculations add huge performance overheads to the data load process. Transformation Execution on HANA BW4HANA has the option to push down data transformation logic to HANA database to improve data acquisition performance. The calculation execution and parallelization while retrieving the data from the database significantly reduces transformation runtime.

In a BW4HANA system, transformations will support both – ABAP and HANA runtime. Once the transformation has been activated, system checks whether the transformation logic can be pushed down to the SAP HANA DB. There is an option in BW4HANA to check whether execution can run in HANA runtime. For custom transformations to be pushed down to SAP HANA database, start, end and expert routine type need to be created as AMDP script (ABAP Managed Database Procedure script). In this blog, I will provide an overview on: Creating AMDP based transformations, how to benchmark it against traditional ABAP routines and discuss its limitations.

How to create an AMDP script based transformation? Step 1: Create an aDSO (Advanced Data Store Object) with activate data and write change log as shown below in SAP BW Modeling tool (BWMT) in Eclipse. Met - Art Fine Photography - Tinux.
