2875519 - Error with Outbound User when configuring Communication Arrangement

You are creating a Communication Arrangement containing an Outbound Service and after assigning a Communication System one of the following errors is presented:

"The communication system doesn't contain any suitable outbound user"  or  "No User/Certificate found"

 SAP S/4HANA Cloud Public Edition

Cause 1:

If you have already defined an Outbound User, it might be that the changes made to the Communication System to specify the Outbound User have not been saved.

Cause 2:

If you're not using Outbound User, this is the expected behavior.

The Outbound and Inbound Communication in the Communication Arrangement is derived from the Scenario that you choose during the creation.

In the Scenario chosen by you it is mandatory to have Outbound and Inbound Communications, even though you will not use one of them.

If you have the "Inbound Only" flag checked in your Communication System, please note that it doesn't have relationship with the Communication Arrangement, it only says that the Communication System is Inbound Only and therefore doesn't have Users for Outbound Comm.

However, in order to use the Scenario ID, you'll need to set up an user for Outbound Communication.

Solution 1:

Save all outstanding changes made to the Communication System assigned to the Communication Arrangement. Retry assigning a user to the Outbound Communication details of the Communication Arrangement.

Solution 2:

In order to create the Comm. Arrangement using the Scenario ID it's necessary to have an Outbound User.

For this, you will need to adjust your Communication System or create a new one including Outbound User.
