Integration Center - DynamicGroupDefinition - No Data

[crisdagosto]

Hello,

in Platform Feature Settings I have enabled the flag 'Enable Dynamic Group Definition Report' and executed OData API Metadata Refresh.

I am trying to create a report using Integration Center and using the DynamicGroupDefinition - have not done anything fancy in the report, just selected all the fields and getting a 'No Data' in the 'Configure Fields'?

I am assigned within 'Manage Role-Based Permission Access' and I have added myself to the API role (I also have the Super Admin role).

I executed the same steps for another client and I was able to see the details of the Permission Groups - what am I missing? 

Thanks in advance for any help you can provide,

Kind regards,

Cristiana
