I am running an end-to-end connectivity test report on C4C. It goes to ECC via CPI and SCC. The report successfully runs when I am using Basic Auth on the IFlow (Check Connectivity to SAP Business Suite) receiver config:
However, because we are connecting via SCC, the Authentication should work when set to None but it doesn't. As per my understanding, because the SCC creates a private tunnel between ECC and integration tenant, we shouldn't have to use any authentication between CPI and ECC. SCC should trust both cloud system as well as backend system (on-prem) if I I don't have any allow list setup for trusted connections.
Here's the screenshot of the ECC webservice config:
Do I need to maintain any certificates in SCC trust store?
NOTE: I have already imported CPI client cert into STRUST and mapped the CPI cert to the integration user in ECC.
