Filter by same period last year (data import)

I connect to a data set that is very heavy, so I have to limit each data import to the previous 30 days. 

 

I do one data import for the previous 30 days this year using the standard date filters. I also want to do a separate data import for the same 30 days last year. It's the data import from last year that I haven't figured out how to do. Any suggestions?

 

Query 1 : 2022/11/08 - 2022/10/10

Query 2 : 2021/11/08 - 2021/10/10

 

Thank you!

Hi  @Anders_G ,

What data source you are connecting to? Please check if  Power Query Parameter can help you achieve the requirement.

1. Handle with filtering when load the data

Include Parameters within Power BI to Query a SQL Data Source

(x as text, y as text)=>let
    Source = Sql.Database("x", "y", [Query="select *#(lf)from z#(lf)WHERE [period_number]="&P2&"#(lf)AND [fiscal_year]="&P1&""])
in
    Source

2. Filter the rows after the data loaded

Using Query Parameters in Filter Rows

@Anders_G , You can get 4 dates like this in power query and use that to filter data

 

Date.From(DateTime.LocalNow())


Date.AddDays(Date.From(DateTime.LocalNow()),-30)

 

Date.AddYears(Date.From(DateTime.LocalNow()),-1)


Date.AddYears(Date.AddDays(Date.From(DateTime.LocalNow()),-30),-1)

Thank you. But where exactly do I add this?
