You are conflating SAP the company with SAP the ERP with SAP the NetWeaver/ABAP platform. From my experience the actual platform, while certainly showing its age, is surprisingly well designed and still very much relevant, despite SAP the company doing its best to replace it with something “modern”/“nosql”/“bigdata”/buzzword-of-the-day. I think that it would do good to many web-oriented developers to study how SAP/ABAP works, because it follows the web-style request/response + background tasks architecture since it’s inception. One interesting thing is that the low-level network protocol used by NetWeaver is ugly undocumented binary thing that you are supposed to use through binary blob, but API of said binary blob has very much the “POST random JSON somewhere and get JSON back” feeling. For the ERP itself there are many people downthread saying exactly same thing: the ERP works and is well thought-out. And almost always breaks horribly when you start to customize it to match your random ad-hoc business processes.
