Dax help- Take value from multiple columns and create single column with multiple rows

Hi sbw666 ,

Based on the information you have provided, you can follow the steps below:

1.Unpivoted Row1, Row2 and Row3 in Power Query.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXJOLElNzy+qVEDhGCFzjJVidaKVjHDKmwA5YCVmyKKmIFGQRCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Invoice Type" = _t, Row1 = _t, Row2 = _t, Row3 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Invoice Type", Int64.Type}, {"Row1", type text}, {"Row2", type text}, {"Row3", type text}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Invoice Type"}, "Attribute", "Value"),
    #"Removed Bottom Rows" = Table.RemoveLastN(#"Unpivoted Columns",2),
    #"Removed Alternate Rows" = Table.AlternateRows(#"Removed Bottom Rows",5,1,6),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Alternate Rows",{{"Value", "Category"}}),
    #"Removed Columns" = Table.RemoveColumns(#"Renamed Columns",{"Attribute"})
in
    #"Removed Columns"

 2.Use measure to calculate Total Amount by Invoice Type.

Total Amount = 
CALCULATE (
    SUM ( Table3[Amount] ),
    FILTER (
        ALL ( 'Table' ),
        'Table'[Invoice Type] = SELECTEDVALUE ( 'Table'[Invoice Type] )
    )
)
