The Journey Continues – Episode 4 of 10

Enterprise Architects are always looking at reducing complexity in an organization. This can happen through implementing or reducing business processes and technology. Episode 4 in the ASUG webinar series, presented by Uwe Grigoleit, from SAP, dealt with the topic of how S/4 HANA can help reduce complexity. This webinar shows where S/4 HANA fits into the bigger ERP picture and the impact on your computing infrastructure.

At the start of the webinar, Grigoleit set the stage by reviewing the background on what SAP is trying to accomplish by moving to S/4 HANA. Enterprise Architects need to appreciate where the complexity lies in their organizations. I think that much of this thinking applies outside of your SAP systems too.

The presenter also reviewed the build up to S/4 HANA with a brief history of SAP HANA:

One point that was clarified for me was exactly how SAP S/4 HANA is able to get the data savings that we hear so much about. I have worked at a couple of different organizations that, over time, have had a challenge with an ever-expanding SAP data footprint. In the presentation slides, Grigoleit showed a logical progression from normal ERP scenarios to those based on SAP HANA, and finally on S/4 HANA. The data savings are huge! This impacts the operations of the system from the backups to disaster recover times. Having less data to deal with on a continuous basis is a big cost saver. With complexity comes cost.

The details on how you can go from a typical 580GB ERP database to less that 10GB was covered in the presentation. It is not magic, and the space savings are dramatic. So what’s the catch? You are only working with what you need on a simplified data structure.  If you have experienced this type of savings be sure to comment so that others know it is real.

Grigoleit then went on to explain the different aspects of S/4 HANA from integration to implementation. SAP has a few different scenarios that they see customers implementing S/4 HANA in. As an Enterprise Architect, you need to be aware that they have these scenarios so you can make the right recommendations on the overall architecture. Yes, these scenarios include hybrid implementations utilizing the cloud and on-premises technology.

I really liked the slide deck that was used by the presenter as it was broken down into a logical progression of why S/4 HANA and then how to get there from many angles. Make sure you download the slides!

The presentation was an overview from a high level, our next webinar, on September 8th, dives deeper into how you can extend your SAP HANA system by building applications and leveraging the SAP HANA Cloud. I am told there will be live demos so make sure you register and attend.

What was the one key take away from the attendees?:

  • Reinforces what have already been shown in presentations before
  • Integration aspects of S/4 HANA with other applications
  • S4 Hana reduces the data footprint tremendously.
  • Compatibility Views make the transition easier!
  • This was a good informational session. Answered many questions
  • Understanding of stages of development of HANA and what is added in each stage
  • What S/4 HANA offers that’s different than the current HANA platform
  • HANA should greatly simplify our company’s information technology operations.
  • The most meaningful was the migration path options
  • Great information regarding what S4HANA and its implied data model. Thank you very much for sharing.
  • Single codeline for Cloud and On-premise
  • Access to additional information for when we decide to migrate from our existing landscape to HANA
  • Good informative webcast! Got to learn much more about S4/HANA
