I have a very simple query that is essentially just filtering a data set but it seems to be taking a long time.
Can anyone see why this is taking so long just to do some basic minipulation of a not very large data set (1500 rows).
let
Source = Excel.CurrentWorkbook(){[Name="BPC_Cost"]}[Content],
#"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"EBITDA #", type any}, {"Lookup", type text}, {"Profit Centre", type text}, {"Cost Centre", type text}, {"Currency", type text}, {"Company Code", type text}, {"Account", type text}, {"Reference", type text}, {"Column9", type any}, {"1", type any}, {"2", type any}, {"3", type any}, {"4", type any}, {"5", type any}, {"6", type any}, {"7", type any}, {"8", type any}, {"9", type any}, {"10", type any}, {"11", type any}, {"12", type any}, {"13", type any}, {"1-avg", type any}, {"2-avg", type any}, {"3-avg", type any}, {"4-avg", type any}, {"5-avg", type any}, {"6-avg", type any}, {"7-avg", type any}, {"8-avg", type any}, {"9-avg", type any}, {"10-avg", type any}, {"11-avg", type any}, {"12-avg", type any}, {"13-avg", type any}}),
#"Filtered Rows1" = Table.SelectRows(#"Changed Type", each ([#"EBITDA #"] <> null and [#"EBITDA #"] <> "Named Range End")),
#"Added Custom" = Table.AddColumn(#"Filtered Rows1", "Tab Name", each "BPC_Costs"),
#"Reordered Columns" = Table.ReorderColumns(#"Added Custom",{"Tab Name", "EBITDA #", "Lookup", "Profit Centre", "Cost Centre", "Currency", "Company Code", "Account", "Reference", "Column9", "1", "2", "3", "4", "5", "6", "7", "8", "9","10","11","12","13","1-avg","2-avg","3-avg","4-avg","5-avg","6-avg","7-avg","8-avg","9-avg","10-avg","11-avg","12-avg","13-avg"})
in
#"Reordered Columns"
I have noticed I get a much quicker perfomance when I load the data to a new sheet as opposed to an existing sheet alongside the source data. Is there any reason for this?
Solved! Go to Solution.
There is no need to reorder columns. Power BI will ignore that and show columns alphabetically.
let
Source = Excel.CurrentWorkbook(){[Name="BPC_Cost"]}[Content],
#"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
#"Filtered Rows1" = Table.SelectRows(#"Promoted Headers" , each ([#"EBITDA #"] ?? "Named Range End") <> "Named Range End")),
#"Added Custom" = Table.AddColumn(#"Filtered Rows1", "Tab Name", each "BPC_Costs")
in
#"Added Custom"
