How can I retrieve information about cases instead of opportunities from CRM Dynamics?

[brissae]

Hello everyone, 

I am trying to do some reports from CRM Dynamics, the integration is already made but I need data about cases instead of Opportunities, I don´t know how I can obtain this information, is there another OData? I am new with power BI and CRM, recently posted same question on a Dynamics Forum.

Hope you can help me, thank you in advance.
