Dynamic Lookup Table

I am trying to create a lookup table that will contain 2 columns (projectID, activeMonth) from a main table of Projects that lists start and end dates (could be empty if project is still active). I want a lookup table that will tell me if the project was active during a specific month (up to 48 months back from date of report). I know how I would programtically iterate through each project row then check if it was active during any of the past 48 month, however, I can't think about how I would do this with DAX. If a project was only active for 3 months then it will only have 3 rows in the ActiveMonth table. Any ideas? Thanks!

Hi @tohare85

 

This should be doable using Query Editor and DAX formulas.  Share a dataset and show the expected result.
