Hi Jasmin,
My layman interpretation of the proxy creation - ADT faciltate the linkage of the ABAP application server with the HANA DB which allows us to create the proxy. For this case, ABAP apps server is hosting the HANA as primary DB.
In a side car approach, there is no ABAP apps server but only a standalone HANA DB. In such situation, only possibility is creating the proxy natively in HANA without using ABAP. If this is feasible, please share the know-how. It will benefits us...
Thanks.
