Please attach your sample data as twbx format.
Is this a Parameter or Quick Filter?
If Parameter and it's a Date Picker, you can convert the Date Picker to the first of the month:
DATETRUNC("month", [Date Picker])
Place Practice Name onto Rows shelf.
Then make a new calculated field:
SUM(IF [Record Date] >= DATETRUNC("month", [Date Picker]) THEN [Number of Records] END) = 0
and filter on TRUE. Hopefully this will suffice!
Are you going to user start date and end date kind of things or selected month data only.
Normal filter can work in your case.
Start date and end date.
