Filtering using a condition on another column in M and in DAX

[Merleau]

Hello,

I need help to filter a table both in M and in DAX.

My original table looks like:

ID	Date	Other columns	Location	Other Columns
1	10/11/2018		Domestic
4	10/12/2019		International
2	5/13/2020		Domestic
4	1/14/2020		International
6	10/15/2018		Domestic

I would like to select only rows where date is before Feb 15, 2020 if the location is “Domestic” or before Dec 15, 2019 if the location is “International”.

I need the solution both in M and in DAX.

The final table should look like:

ID	Date	Other columns	Location	Other Columns
1	10/11/2018		Domestic
4	10/12/2019		International
6	10/15/2018		Domestic

In M, I tried the following, but the result is all wrong.

#"Filtered Rows" = Table.SelectRows(#"Source", each ( if [Location]="Domestic" then [Date] < #date(2020, 15, 2) else [Date] < #date(2019, 15, 12) ) ),

I have no idea how to go about it in DAX.

Can somebody pls help?

Thank you

Hello @Merleau 

this is the solution for Power query

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTI00Dc01DcyMLQEclzyc1OLSzKTlWJ1opVMoLJGMFnPvJLUorzEksz8vMQcsBIjoKipvqExUIWRAVb9+oYmMElM7WZQG0xBNlig6I8FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Date = _t, Location = _t]),
    Trans = Table.TransformColumns(Source,{"Date",each Date.From(_, "en-US" )}),
    SelRows = Table.SelectRows(Trans, each (_[Location]="Domestic" and _[Date] < #date(2020, 2, 15)) or (_[Location]="International" and _[Date] < #date(2019,12,15)))
in
    SelRows

in DAX you can add a new column like this and filter in the visuals

FilterColumn = if ( and([Location]="Domestic", [Date]<date(2020,2,15)),TRUE(), if (and([Location]="International", [Date]<date(2019,12,15)),true,false))

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
