I am NEW to Power BI and DAX. I am trying to write a measure and place it in a matrix that filters a list of customers based upon selected dates within a slicer (a customer must be a customer in ALL dates selected). For example, if I have five customers, and I select the dates 01/01/2020, 05/01/2020, and 08/01/2020, and only three out of the five customers made a purchase in EACH of the three selected dates, then I only want to see the list of those three customers. Any thoughts about how I could write a measure that will accomplish this?
Thank you,
Thank you,
