Hello Satyam,

The error you are receiving is based on the following:

The user does not have a legitimate relationship with the request or service.

Hi Balal,

Thanks for your reply. I have since reviewed the linked post and gone through the set-up on our INT eRS environment, however, we are still facing the same issue with the same response message of no relationship despite the workgroup consisting of all the test accounts that are in use.

Are you or anyone from the team able to support the resolution of this issue through a teams call?

Kind regards,

Satyam
