Does OData adapter support principal propagation?

[former_member207065]

Hi experts,

In integrated configuration, when I click tab 'Outbound Processing' and select my OData channel which uses OData adapter, the 'Propagate Principal' option isn't available. So does that means OData adapter doesn't support principal propagation?

I need principal propagation to configure single sign-on from sender to receiver. The receiver provides OData interfaces. Luckily SAP has OData adapter, but unlukily the OData adapter seems not support principal propagation. How will you do in such case?

Thank you in advance

Hi Abe,

Seems like the only adapters supporting Principal Propagation are:
RFC Adapter
SOAP Adapter
Web Service Adapter

At least according to the documentation (see second note)

Hi Jacob,

Thank you for your reply. I think the documentation was not updated. E.g., the REST adapter also has the 'Propagate Principal' option.

By the way, how do you usually do if you want to log on the receiver with the same logged-on user in sender?

Best regards,

Hi Abe,

We are in the fortunate situation where we don't have this business requirement. Most of our integrations in SAP PO are A2A/B2B without end-user initiating the communication.

For end-user online calls we use SAP Gateway exposing backend services as OData.

Hi Jacob,

I am also considering using SAP Gateway to expose interface to frontend. But if frontend wants to call non-SAP backend system, I guess we can't go through SAP Gateway, or not easy.

Hi Abe,

I'm not fluent in the capabilities of SAP Netweaver Gateway, so I'm not sure how it handles requests to non-SAP backend system.

An alternative for you could be to look into API Management - it should give you the possibility to expose both SAP and non-SAP backends in a unified, web-centric way.
