HI Team,

The Customer have ECC System we can Use ODATA Service using the SEGW Tcode in ECC or Gateway Environment . if Customer have HANA Database we can Use HANA XS OData Service. if the ECC System Means we can Use BAPI and Standard Tables for Service Creation. how we can use standard Business Process in XS ODATA Service

HI Florian,

Thanks now i understand the Architecture of SAP. but still i have one question. in which scenario i can go with XS Odata Services for Develop the Fiori Application. if i am not wrong Customer Dont have ABAP Backend Server,but they have FIori App Component like ERP other systems in the Cloud.

W/o knowing the system landscape, I can of course not give a concrete answer to your specific case.

But some examples would be to go with an XSOData service, if you develop a Fiori Application running on HANA (XSC or XSA) or imlementing a Fiori App running on SCP using only HANA as backend.

XSOData is the way to create an OData service directly on a HANA database. That is for HANA native development. That means that you have no access to any kind of business logic writting in ABAP provided by modules running on an ECC system. With an XSOData service you can just access the tables below that business processes, which are available in the corresponding ECC system schema on HANA.

Thanks Florian,

I got it, one more things if i am going to activate one Fiori App In ECC I need to Activate front end & Backend Component in Ecc the System , In Same scenario how we can Achive in XS Odata Service

[pfefferf]

First of course the OData service (either XS Classic or XS Advanced) need to be active/deployed. If you wanna use that service within an Fiori App running on a Fiori Frontend Server, then you need to configure a Web Dispatcher to route the accesses to the HANA XS(A) engine.
