Symptom
When creating a Communication Arrangment the following errors could be seen:
-
Auth. method not supported
- The scenario doesn't support this authentication method
Environment
SAP S/4HANA Cloud Public Edition
Reproducing the Issue
-
Create a communication system in the Communication Systems app, specifying a new inbound communication user
- Create a new communication arrangment in the Communication Arrangments app
- Set the communication system of the new arrangment to the one that you created in step 1
- At this point the user won't be selected, and if you attempt to select a user for the inbound service, you will see the errors
Cause
-
Some communications scenarios only support specific authentication methods
- As an example, SAP_COM_0013 only supports OAuth2, so if the communciation user was created to use username and password, the error will occur
Resolution
-
Go back to the Communication Systems app
- Create a new user, or edit your current inbound service communication user
- Set the authentication method to be the required authentication type for the specific communication scenario that you are using
