% of complete by high level grouping in PowerBI?

[pavanbits sphs]

I'm new to Power BI and looking for any help I can get. I'll try to keep this short and to the point:

My data set for Power BI is just a big list containing (but not limited to) users, training courses, training programs, and completion statuses.

A training program is comprised of multiple training courses.

All I'm trying to do is put together a table that shows me a training program completion % for each user and which training courses they have yet to complete. So for example, Training Program 1 is comprised of 10 training courses. If a user has completed courses 1-7, then their Program Completion % would be 70%. Then 3 courses would be displayed as incomplete, courses 8-10.

I've tried numerous DAX measures to accomplish this and they either only work partially or don't work at all.

Happy to provide a test .pbix file for context and/or an example of the DAX measures I'm using so far, but posting without them initially so I don't confuse anyone trying to help.
