Display Value from list that matches another column

Hi, I am new to Power BI and trying to query the data and effectively display the information I am after. After the Data is extracted, I need to confirm which specific values exist in a List Column...

    Use the below formula in a custom column

     

    = List.Intersect({[ListData],Table2[VersionName]}){0}

    In case, second table doesn't have the required element, then you can display null by following formula

    = try List.Intersect({[ListData],Table2[VersionName]}){0} otherwise null

     

    See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test

     

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjY1MTNX0lFyzCnISLRWcCnNS7VWCErMS8nPBfLy060VnHJKU5VidaKVTEwtLEFKfRKrKq0VfBNLkjOsFdwTc3MTQVRRUmI6RJ2RsZm5BUhdfnEJUHtqCVDeIzWnQCk2FgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [TicketNumber = _t, DelimitedData = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"TicketNumber", Int64.Type}, {"DelimitedData", type text}}),
        #"Added Custom" = Table.AddColumn(#"Changed Type", "ListData", each Text.Split([DelimitedData],"; ")),
        #"Added Custom1" = Table.AddColumn(#"Added Custom", "Version", each List.Intersect({[ListData],Table2[VersionName]}){0})
    in
        #"Added Custom1"
