What SAP roles are required for an user to access /sap/xi/engine from CPI

[MounikaR]

Hi Team,

We have been migration our PO interfaces to CPI and we are using Basic authentication to connect with SAP systems.

While migrating proxy interfaces we are facing Authorization issues. The user we are using for all other communications is giving error '401- Unauthorized' when tried to access /sap/xi/engine.

What roles are required here? what options are available?

If the user works from your PO system, then the credentials have been entered into the security material incorrectly.
