Hello, How can i recreate the Calculation Coumn shown in the image below in Power Query, in a way that it can be done automatically if any new Assessment Unit was added?

Thank you.

Hi,

Go to Home then select Advanced Editor. Copy and and past following M code. Then you can get an idea how to do it.

Please note that if there is more than one A2 to one Assesment you will get a wrong answer.

Without seen your dataset its hard to give the best solution.

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WilDSUXI0BBJGSrE6UK4RkDBEcI2BhAGYGwlTbIngghRbILggxeZgbhRMsRmCC1JsguCCFBsrxcYCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Assessment = _t, RF = _t, Value = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Assessment", type text}, {"RF", type text}, {"Value", Int64.Type}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Assessment"}, {{"Count", each _, type table [Assessment=nullable text, RF=nullable text, Value=nullable number]}}),
#"Duplicated Column" = Table.DuplicateColumn(#"Grouped Rows", "Count", "Count - Copy"),
#"Added Custom" = Table.AddColumn(#"Duplicated Column", "Custom", each Table.SelectRows([#"Count - Copy"], each ([RF] = "A2"))),
#"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"Value"}, {"Value"}),
#"Removed Columns" = Table.RemoveColumns(#"Expanded Custom",{"Count - Copy"}),
#"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Value", "RFValue"}}),
#"Expanded Count" = Table.ExpandTableColumn(#"Renamed Columns", "Count", {"RF", "Value"}, {"RF", "Value"}),
#"Changed Type1" = Table.TransformColumnTypes(#"Expanded Count",{{"RFValue", type number}}),
#"Inserted Multiplication" = Table.AddColumn(#"Changed Type1", "Multiplication", each [Value] * [RFValue], type number),
#"Renamed Columns1" = Table.RenameColumns(#"Inserted Multiplication",{{"Multiplication", "Calculation"}})
in
#"Renamed Columns1"

Thank you.

Hi

C4 and Value both reffer same cell.

Could you please check the formula?

Thanks

Hello Dinesh, the formula is (Value C4 x Value where Assessment Unit = Assessment Unit of C4 AND RF = A2),

Basically for each assessment unit, when the RF = A3 i want to calculate its value times the value of A2 that has the same Assessment unit.
