PowerBI: Filter by date

I have a query, which I'd like to filter by the new date column I created.

Basically, anything which is 42 days earlier than that date is accepted.

I've tried doing a filter by date, and then substracting it by 42, but it does not work?

let
    #"SQL-JM" = let
    Source = Sql.Databases("xxx.xxx.xxx.xxx"),
    MNH = Source{[Name="DBT"]}[Data],
    #"DBO-JM" = DBT{[Schema="dbo",Item="DBO-JM"]}[Data]
in
    #"DBO-JM",
    #"Added Custom1" = Table.AddColumn(#"DBO-JM", "Start_of_QTR", each Date.StartOfQuarter(DateTime.LocalNow())),
in
    #"Filtered Rows"

If I understand your task correctly, you don't need custom column at all.

I'd do like that:

let
    #"SQL-JM" = let
    Source = Sql.Databases("xxx.xxx.xxx.xxx"),
    MNH = Source{[Name="DBT"]}[Data],
    #"DBO-JM" = DBT{[Schema="dbo",Item="DBO-JM"]}[Data],
    GetFilterDate = Date.From(Date.StartOfQuarter(DateTime.LocalNow())), //You can use any logic to get that date
    FilterRows = Table.SelectRows(#"DBO-JM", each [DateStamp] < GetFilterDate) //You can also add some modifications to GetFilterDate using each row's values, if you need
in
    FilterRows

Assume that you want to filter by the DateStamp column which 42 days earlier than Start_of_QTR is accepted, you can add the following line after the #"Added Custom1" line:

#"Filtered Rows" = Table.SelectRows(#"Added Custom1", each [DateStamp] < Date.AddDays([Start_of_QTR], -42))
