Dear Experts,

We are trying to extract Material Stock (SAP_COM_164) from S/4 Public Cloud system from CPI via ODATA V2 adapter but getting "403" error. 

In S/4, we have created Communication User (added CPI load balancer certs), Communication System (added the user here for Inbound communication) and then created communication arrangement.

ODATA connector:

Error:

Please suggest here. Our tenant is a trial account.

The HTTP 403 error indicates the server understands the request but won't authorize it, requiring client authentication.

Check and verify the user has necessary roles and authorizations in the Maintain Business Users app. Ensure it's correctly set up, active, and using the right communication scenario and confirm the OData service is activated in the Manage Communication Users app. Check credentials and endpoint URL in the CPI OData V2 adapter and consult your network team for possible restrictions.
