Get last 3 months with DAX

Hi all,

I want to filter a table by Table[latest_send_date] where this column only contains dates from the last 3 months. In another table I want to apply the same filter but then these months 1 year ago. Anyone have an idea how to do this in DAX? Don't get it done..

Thanks!

Hi @Oos 

 

1. I 'd like to suggest you use the slicer rather than Dax to achieve this:

2. Alternatively, you can use the DAX formula as below:(Create a calendar table and manage the relationship with your fact table)

value in last 3 months this year = CALCULATE(MAX('Table 4'[Value]),FILTER('Table 4',[Date].[MonthNo]>=MONTH(TODAY())-3&&[Date].[Year]=YEAR(TODAY())))

value in last 3 months last year = CALCULATE(MAX('Table 4'[Value]),FILTER('Table 4',[Date].[MonthNo]>=MONTH(TODAY())-3&&[Date].[Year]=YEAR(TODAY())-1))

How did you build that slicer with "Last" and designating number of months?  Is that a non-standard slicer?  Thanks
