First Hands on migrated SAP BW to HANA production system

The first test migration to HANA looks good at first glance. The performance of the database is impressive.

But as many features are implemented in SAP BW queries – the performance is not that impressive as I hoped. The monitoring of the queries shows me that the database result is available really fast. But the calculation steps following in ABAP are (still) slow.

Also – this is a first impression of a test-migration:

  • The test-system running the abap-stack isn’t that powerful as our productive server.
  • Many objects are still on the row-store of the HANA (because they are not migrated to in-Memory for several reasons).
