I am struggling to correlate the technologies with the business scenarios. OnPrem, S/4Hana Cloud.
Let's assume I want to create a sales order. Depending on where you look at SAP, each claims it is the sole and best method.
API hub:
SAP graph
RAP
BAPI
Enterprise Messaging
And then there are many more options. My question is, which of these technologies are to be used in what scenario today and in future? Especially in light of the One Data Model initiative which seems to be built around SAP Graph and Enterprise Messaging.
