Here is the question & answer portion of the ASUG webcast we had this past week Empowered Self-Service BI with SAP HANA and Lumira with Honeywell – ASUG Webcast
Q: Is the 1TB of solid state memory or a mix of memory and disk storage...thanks.
A: 1TB is all memory - some disk storage in HANA is used for disaster recovery.
________________________________________________________________
Q: Did you consider using SAP BW versus using HANA directly?''
A: We did have SAP BW in past; and ended up working on that for 2 years, went back to data mart structure - did not consider BW on HANA at that point.
________________________________________________________________
Q: To simply things, do you feel that Design Studio can replace Dashboard?
A: With limited amount of experience with Design Studio - says yes, because it has application capabilities, not just dashboards. Design Studio is more robust now for non-BW environment.
________________________________________________________________
Q: Do you use Analysis for Office (Excel)? If not, why?
A: He does not use that; wishes he could - MS Office Add in for pivot like reports - not used because of firewall architecture
________________________________________________________________
Q: Why would Lumira be dependent on the resource on the client machine? Shouldn't it use the HANA do the analytics?
A: Lumira creates a Sybase database on client machine - that is what is used as the analytic engine. Once in HANA server - heavy liftng goes away.
________________________________________________________________
Q: So you do not use BW Data warehouse at Honeywell? Where is the data from ECC replicated to?
A: Not using BW in their architecture now.
________________________________________________________________
Q: How would you compare this with Tableau and Qlikview
A: Only has limited familiarity with Tableau - but they are going all SAP so Tableau is not a choice
________________________________________________________________
Q: Is Lumira Server available to download for the POC purpose?
A: Lumira Server is not available yet
________________________________________________________________
Q: We saw poor performance with latest LUMIRA vesion with HANA online...are there any future integration improvements in the road map
A: He does not work for SAP - does not know about next roadmap - cannot answer - hope so
________________________________________________________________
Q: Any consideration of building transactional systems directly on top of Hana to support direct, real-time connectivity rather than the extraction model shown?
A: There are considerations for reporting off of HANA tables instead of ECC tables - RDS for HANA - CO-PA Accelerator - instead of using ECC CO-PA tables in ECC and use them in HANA - use GR55 against HANA tables.
________________________________________________________________
Q: What are different tools that you looked into before making a decision to go Lumira?
A: Primary one before HANA was Microstrategy - not real time like HANA. Lumira is an SAP product, Explorer-like
________________________________________________________________
Q: If you were using Lumira agains SAP Hana, why does the client tool, require so much memory? Doesn't HANA do the in memory processing?
A: As mentioned before, HANA is used as a data source, not an analytic engine; analytic engine is on machine
________________________________________________________________
Q: Prior to using HANA you had a mix of ODS's and data Marts. How long did it take you to re-model this data and the data loads for HANA?
A: Started on working on this 2 years ago, then 1 year ago started putting other sets of data on HANA - not everything is there yet.
________________________________________________________________
Q: Before going to HANA have considered the AWS HANA one?
A: no
________________________________________________________________
Q: Do you currently have Enterprise DW and if so are you planning to move EDW to HANA platform.
A: They do have an EDW and do have plans to move it to HANA platform
________________________________________________________________
Q: Can Design Studio be used standalone like Xcelsius i.e. no connection to a database but by using an Excel file to mock up a dashboard, demo dashboarding, prototype a dashbaord?
A: No it cannot
________________________________________________________________
Q: Was the adoption throughout Honeywell presented to "end-users" (entry-level, with little to no analytics background) or to more advanced users?
A: It was introduced to advanced users first, and change thought process of the business (those without the analytic background)
________________________________________________________________
Q: Before going to physical HANA ....have you considered the AWS HANA one?
A: Already answered - no
________________________________________________________________
Q: And as a follow-up... How was adoption for the end-users?
A: Honeywell President says it will be a certain way - adoption rate is high
________________________________________________________________
Q: Can Analysis for OLAP and Analysis for Office both be used to access ECC data replicated via SLT to HANA when not using BW on HANA?
A: Yes
________________________________________________________________
Q: Lumira has a limitation og 10,000 rows or datapoints...how can we increse the limit?
A: He has not seen that limitation and he has a robust machine.
________________________________________________________________
Q: Are their limits to the number of power users that use the tool concurrently? Does it require any type of user management besides just logins, etc.?
A: Because it is a client tool, no limitation as far as number of users - need licenses
________________________________________________________________
Q: Did you have an executive sponsor- IT, business or both? How much effort was there to get buy in to go forward with the work?
A: Have a sponsor from both IT and business.
________________________________________________________________
Q: How many business users are using HANA data? And how many IT SAP developers do you have?
A: Don't have an exact - 5K users
________________________________________________________________
Q: What have you found your HANA compression ratio is, versus your previous database(s)?
A: Previous databases had no compression; current compression is 7.5x
________________________________________________________________
Q: For historical data retention do you have near-line storage system attached to HANA?
A: Do not have NLS yet - discussing
________________________________________________________________
Q: Did the Customer Data Marts vsBW resulted in large implementation time frames and any Data Quality issues?
A: Since not doing BW - can't say.
________________________________________________________________
Q: What version of Lumira did you say is available now?
A: 1.14
