I have been asked for an education advice by the folks from my BW past. In this blog I will discuss the pros and cons of two career options for SAP BI specialists: HANA Modeler vs. S/4HANA Analytics developer. Being both, I am sharing my subjective thoughts.
For those lost what I am talking about, this video will serve a good intro into S/4HANA Analytics.
First things first: what do we believe in?
While technically both modelling approaches are possible on both types of the systems: traditional Business Suite @ HANA and S/4HANA (subject to SP levels), to me it all comes down to the question which type of the systems will prevail in the long run? If I were to believe in S/4 as much as SAP does, certainly the latter will be in majority.
Customer choice between the two
Now, a little situation to decide which approach will the customer take if they have an S/4HANA system. Let us compare pros and cons of using the two different environments:
|HANA Modelling: build Calculation Views||S/4HANA Analytics: build CDS views|
· GUI available!
· Quite mature environment, potentially less bugs
· A lot of literature, courses, best practices
· May be used to build a HANA-native Data Warehouse (subject to licenses)
· Something that SAP bets on
· SAP-delivered content needs 0-installation
· SAP-delivered content is evolving a lot
· CDS views are ABAP entities. Thus, contrary to marketing naming (S/4HANA something), these are DB-agnostic and knowledge reusable
· ABAP-managed users and authorizations
· Enough (nearly-) free education. I will make a separate post on that
· SAP-delivered HANA Live content is not evolving anymore
· In many cases DB users require creation & role admin (aka “red tape”)
· HANA Modelling knowledge is not directly applicable on other DB’s
· Loses out on simplifications (think sFin, sLog, etc.)
· No GUI, only coding. Many consultants will drop out at this point, but is it bad?
· New environment, more bugs, notes, etc.
· Education just starting
· Not suitable for building an integrated Data Warehouse (without BW).
Now, which one will the customer take? In the long run, I think they will follow SAP with their S/4HANA vision and modelling using CDS technology.
All-in-all, if you:
- think S/4HANA implementations will take off
- haven’t invested HANA Modelling education
- don’t mind a bit of coding
taking the S/4HANA Analytics route, i.e. learning to build CDS views and expose them to the preferred front-end(s), makes much of a better sense. Take S4H410 or follow my future blog posts on a (nearly-) free way to obtain the same knowledge.
- think there will be more migrations of existing environments to HANA DB
- have unrecovered investment in HANA modelling education
- willing to wait for a decent GUI for CDS’es (fingers crossed here)
