Defensive battle

The digital transformation is heterogeneous. But the fact is that Christian Klein is fighting with very blunt weapons and so the probability is very high that he will lose the battle.
SAP's Hana database is over ten years old, S/4 is almost as old, and much of the Abap code in S/4 is much older still. Ten years is an eternity in the fast-paced IT scene. E-3 author and DSAG working group spokesman Johannes Szalachy writes about this in detail in the upcoming E-3 February 2022 issue: Is the S/4 Strategy 2022 Still Up to Date?
What is frightening about this scenario is the fact that SAP is planning with Hana and S/4 into 2030 and beyond. Even the best Abap modifications on the Business Technology Platform or in on-prem systems do not turn the old construct into a modern ERP.
SAP urgently needs a rejuvenation, a retread, an ERP relaunch. Unfortunately, the prerequisites for this are not in place, as the community can observe with the example of Signavio (process mining): In order to get the software up and running with existing customers, SAP has to fall back on its old partner Scheer, see E-3 Magazine December/January 2022, page 24.
