2630509 - The Scenario Doesn't Support This Authentication Method


When creating a Communication Arrangment the following errors could be seen:

  • Auth. method not supported
  • The scenario doesn't support this authentication method



Reproducing the Issue

  1. Create a communication system in the Communication Systems app, specifying a new inbound communication user
  2. Create a new communication arrangment in the Communication Arrangments app
  3. Set the communication system of the new arrangment to the one that you created in step 1
  4. 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


  • 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


  1. Go back to the Communication Systems app
  2. Create a new user, or edit your current inbound service communication user
  3. Set the authentication method to be the required authentication type for the specific communication scenario that you are using
