Duplicate table with every combination based on a specific column

[IvanCM]

I have an exisiting table where I need to populate missing rows with no values as per the Current and Required table example below...

Basically, for every entry, there should be every version of the "Timesheet" column, e.g. if only an "Actuals" value exists in the current table, I need the missing row for "Planned" to exist.

Try this.

Pivot the Timesheet Column using Hours as values ("Dont Aggregate")

replace nulls with zero

Unpivot the Actuals and planned columns

Please see attached file for steps

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjDU9UrM0zW0VNJRcgTh5JLSxJxiIMtCKVYHUz4gJzEvLzUFyLKEyBsh5J1Q9BsaYBjgTMACZ3QLYgE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Date = _t, Name = _t, Timesheet = _t, Hours = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Name", type text}, {"Timesheet", type text}, {"Hours", Int64.Type}}),
    #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Timesheet]), "Timesheet", "Hours"),
    #"Replaced Value" = Table.ReplaceValue(#"Pivoted Column",null,0,Replacer.ReplaceValue,{"Planned"}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Replaced Value", {"Date", "Name"}, "Attribute", "Value")
in
    #"Unpivoted Columns"

Worked exactly as I wanted!
