Certificate based authentication between C4C and CPI

[former_member603506]

Hi All,

We are trying to set up the certificate based authentication between HCI and C4C for our BP replication scenario from S/4 On prem to C4C system.

Steps we followed:

1. Downloaded the certificates from HCI- Second Option in the below note

(Followed the note
https://launchpad.support.sap.com/#/notes/0002660023
)

2. Uploaded the certificate in C4C Trust list.

3. In the communication arrangement, we have uploaded the root certificate that was downloaded from step 1

Note: In CPI as well as C4C, authentication type is set to Certificate based.

Now when we send the Business partner from S/4, it reached CPI successfully. But in CPI, we are getting below error message and the message is not reaching C4C.

org.apache.cxf.interceptor.Fault: Could not send Message., cause: org.apache.cxf.transport.http.HTTPException: HTTP response '401: Unauthorized' when communicating with https://myXXXXXX.crm.ondemand.com:443/sap/bc/srt/scs/sap/businesspartnerreplicationin

Please suggest the possible solution.

Regards,

Mohit
