Error - No change request is assigned to you

Hello,

We're trying to implement Flight Data Model example provided by SAP at Configuring Master Data Governance for Custom Objects - Master Data Governance - SAP Library 

But we get the attached error when running the example

Error: No change request is assigned to you

We already rechecked that we have assigned all the authorization objects mentioned in the example to users.

Can anyone help us understand what the issue may be

Thanks,

Sagar Dixit
