Filtering a table in a cascading relationship

hi  AlexKahler 

From your screenshot of relationship, it should works well.

I think the problem should be that

Master Date table is used DAX, so it will only have 12:00:00AM time for each date,

[Visit date & time] must have different time not just 12:00:00AM time for each date,

you just change the format of them to make them same.

So although you have create a relationship between them, but they are not same for each date.

Just add a date column for [Visit date & time]

Date = DATE(YEAR([Visit date & time]),MONTH([Visit date & time]),DAY([Visit date & time]))

Then use this column to create a relationship instead of [Visit date & time].

Now it should work well.
