Null Values and dates not within time period

[ArthurDavid]

Hi,

I'm somewhat stumped on a piece of reporting I've been asked to build. I have three linked tables - a list of locations, a list of incidents recorded by those locations and a date table. What I'm being asked for is a list of locations that have not reported an incident in the last 12 months.

I can put a simple filter on count of cases to show Null values against the list of locations, but that's nothing ever submitted, and I have an expression built to identify if the case is within the last 12 months (isLast12Months = IF('All Complaints'[Complaint Date] > MAX('All Complaints'[Complaint Date])-365,1,0) but I'm struggling to connect them together.

Any thoughts appreciated!

Hi, @ArthurDavid 

Can you provide sample data for testing? Sensitive information can be removed in advance. What kind of expected results do you expect? You can also show it with pictures or Excel. I look forward to your response.
