Hello Scott!
When you create a 2-way integration between Jira and PractiTest, you’re able to map most of the relevant Jira system/custom fields with the equivalent PractiTest fields.
This should allow you to use PractiTest’s Report Center for generating any relevant report with the data both from PractiTest and Jira as well.
You can read here about the fields’ mapping:
We also have a Requirement Traceability Report, which will provide you full Traceability from Requirements to Issues - including those that are integrated with Jira:

As of the Automation with Power BI, this part is less our expertise besides the knowledge that the integration between it and PractiTest is possible via our Open API
I’d highly recommend to consult with our Customer Success and/or Customer Support department - maybe a short session with their representatives will lead you to the optimal solution.
Best Regards,
Alex Gruzglin
