SAP BI Blog 
Hello Jonathan,
This is really a wonderful blog. Iam looking for questionnaire on BW-HANA for asking to customer after they decide to move onto BW-HANA. Can you help me in this?
I am currently working on a SAP BW powered by HANA and HANA standalone Pilot in Ramp-up. At the moment I don’t have any questionnaires. Why types of questions were you looking for?
Well i am looking for What kind of questions we need to post to the customers before taking up the assignment for BW-HANA. Do you have any standard kind of template? How are your Rampup projects going on?
Do send me a mail to tlswaroop@gmail.com
Krishna,
My projects have focused on HANA standalone. My last project did include BW powered by HANA but that was managed directly by SAP and I managed the Data Services, BOBJ and HANA content portion. Based on my observations the process of migrating from one BW system (based on DB2 in this case) to the new NetWeaver 7.3 powered by HANA system was straight forward. However, there were several BW and HANA tuning issues that had to be addressed post migration. The main purposes for the client to move to BW powered by HANA was based on the need to increase the response time associated with large InfoCube BEx queries. Given that the BW Powered by HANA solution works much like previous BW systems (based on any DB), I would assume many of the same questions still apply. However, an experienced SAP BW powered by HANA implementer might have more input.
Thanks,
Thank you very much for sharing! A client is thinking of implementing SAP HANA standalone and wonders if they should move their BW System onto HANA or rebuild the reports. Considerations: The BW reports are not many and they cover the information partially (for example, they are only covering sales to the US, but they also want to include sales to EMEA in the Standalone reporting).. Can the two environments coexist? What would you advise? Thank you in advance. Greetings!
Lean,
If they purchase the SAP HANA Enterprise License (Not limited use), they can use SAP HANA to power BW and to host data marts. Some at SAP do not like using a single instance of HANA to host BW and a data mart, but if you manage it correctly, it will work perfectly. If you go this route, the customer will find it to be an easy transition. Keep the BW content and then build new HANA native content on a per project basis.
