I have a table with dates, and I want to filter the table to only show values where the date is older than 30 days (as of today). How do I do this?
Solved! Go to Solution.
Hi
You can add a calculated column to your dates table with a formula that checks whether the day falls within the last 30 days. You can then filter your visuals with this column.
Last30Days =
IF(
DATEDIFF(Dates[Date],TODAY(),DAY) <=30,
TRUE(),
FALSE())Hope this helps (if so please give a kudo)

Thanks for the suggestion - I've tried to do this, but when I input the formula I get the following error message:
"Expression error: The name 'IF' wasn't recognized. Make sure it's spelled correctly."
Any idea why? I can't seem to find another way of doing this
Hi,
The formula suggested is a measure. Go to Modelling > New Measure. You are writing that formula in the Query Editor.
