Custom Fiori App with 2 SAP backend

[former_member592282]

Hello Experts,

I have to develop one custom Fiori application with 2 SAP backend system e.g. CRM & ECC system. Scenario is to capture some fields from Fiori Frontend UI & save in both the system CRM & ECC tables via OData, can you please confirm, if this is possible? and what is the best way to do it? Is there any chances of authentication issue with this design? Is this kind of architecture recommended with Fiori?

Thanks in advance!

Regards,

Ravi

Hi Ravi,

I see three Options:

1.) SAP Fiori apps can consume data from several OData services as described here:

2.) Depending on the scenario I would check if it wouldn't be an idea to implement the service in just one system (for example your ECC) and call the CRM from within the service implementation in ECC by performing an RFC call.

3.) You can develop a Service in the SAP Gateway Hub that performs RFC calls to both, the ECC and the CRM backend.
