Road to BW4/HANA
This blog is about how we migrated from BW7.4 on HANA to BW4/HANA. It will commence in a number of blogs to keep the length down, and make it a little more manageable for reading.
This blog is focuses on the second – “SAP BW 7.4 powered by SAP HANA”, and first part of the third “SAP BW 7.5 powered by SAP HANA”.
We have a native HANA 1 revision 96 deployment and BW7.4 SP8 on HANA, each with their own separate HANA database instances. We wish to integrate data from two non-SAP sources with our native HANA deployment for management reporting.
The key here, is Management Reporting. If we only need operational reporting, then we would likely integrate the other two systems using HANA SDA, however, for our management, we are interested in historic data, and wish to keep our native HANA system separate.
We set out creating a proof of concept project for which we gave three months. We are currently 6 weeks in, and delayed 3 weeks due to BW4HANA not being able to utilize our existing BW license. To assist with any issues, we successfully registered with SAP for the Early Adoption Care program. This gives us priority help if issues are discovered. I would recommend this to anyone considering BW4/HANA in the next half year.
My main focus is in the BW space. BASIS tasks, e.g the NetWeaver upgrade, was performed by my colleague Claire Richards, which I will not go into any detail here, but link to the blog she is writing simultaneously.
