A nice thing about S/4HANA is that taking all old Z-programs with is not an option. Only a handful that are API based. Updates to SAP tables are also blocked technically now (I tried - it did not work with ABAP native commands).
That's interesting. I haven't been connected to S4/HANA system yet. Are you saying that the developers are blocked from accessing tables directly? That makes sense but I am wondering how it's done.
Cheers
