1. Download the json file.
2. Import this to Postman.
3. Use the technical user "ABC" you want to.
4. Send.
5. Error message appears: "The data service request has been understood, but it is refused. User is successfully authenticated. The request SHOULD NOT be repeated."

The issue is that for the communication arrangement, you have assigned all available services.
Ideally you should assign only services which is required for the user.

You should only assign the required service and it should work.
