PowerBI 쿼리 지원이 필요합니다.

Question

데이터가있는 4 개의 Excel 통합 문서가 들어있는 "Link_StaffDataLocation"폴더를 찾는 PowerBI에서 쿼리를 만들려고했습니다. 이러한 통합 문서의 데이터는 부적절한 방식으로 구성되기 때문에 데이터를 재구성하여 단일 테이블에 추가하려고합니다.

나는 아래에서 시도했다. 그것은 나에게 길의 일부를주는 것처럼 보인다. 그러나 그것은 첫 번째 통합 문서의 데이터 일 뿐이며, 나는 내 테이블에 4 번 이상 계속 들어갑니다.

나는 무엇을보고/이해하지 못합니까 ??

let 

//Get data from file in folder 
Source = Folder.Files(Link_StaffDataLocation), 
#"Get the files" = Table.SelectRows(Source, each [Extension] = ".csv" or [Extension] = ".txt" or Text.StartsWith([Extension], ".xls")), 
#"Removed Columns" = Table.RemoveColumns(#"Get the files",{"Date accessed", "Date modified", "Date created", "Attributes", "Folder Path"}), 
GetExcelContentIntoColumn = Table.AddColumn(#"Removed Columns", "Custom", each if Text.StartsWith([Extension], ".xls") then Excel.Workbook([Content]) else null), 
ExpandContent = Table.ExpandTableColumn(GetExcelContentIntoColumn, "Custom", {"Name", "Data", "Kind"}, {"Custom.Name", "Custom.Data", "Custom.Kind"}), 
#"Filtered Rows" = Table.SelectRows(ExpandContent, each ([Custom.Name] = "BC Ongoing Projects")), 

//Create files name list 
FileNameListStep1 = Table.Column(#"Filtered Rows","Name"), 
CurrentFilename = FileNameListStep1{0}, 

//Filter on first filename 
IterationFunction = (CurrentFilename) => 
let 
    FilterOneDataSetAtATime = Table.SelectRows(#"Filtered Rows", each ([Name] = CurrentFilename)), 
    // Make necessary adjustments to data 
    #"Custom Data1" = #"Filtered Rows"{0}[Custom.Data], 
    #"Filtered Rows1" = Table.SelectRows(#"Custom Data1", each ([Column1] <> null and [Column1] <> "BC Ongoing Projects" and [Column1] <> "Filters Used To Select These Practitioners:" and [Column1] <> "Pract" and [Column1] <> "Scheduled Hours" and [Column1] <> "Total:")), 
    #"Removed Columns1" = Table.RemoveColumns(#"Filtered Rows1",{"Column5"}), 
    #"Replaced Value_DK" = Table.ReplaceValue(#"Removed Columns1","DK","",Replacer.ReplaceText,{"Column4"}), 
    #"Replaced Value_SE" = Table.ReplaceValue(#"Replaced Value_DK","SE","",Replacer.ReplaceText,{"Column4"}), 
    #"Replaced Value" = Table.ReplaceValue(#"Replaced Value_SE",null,0,Replacer.ReplaceValue,{"Column6", "Column7", "Column8", "Column9", "Column10", "Column11", "Column12", "Column13", "Column14", "Column15", "Column16", "Column17"}), 
    #"Changed Type" = Table.TransformColumnTypes(#"Replaced Value",{{"Column6", type text}, {"Column7", type text}, {"Column8", type text}, {"Column9", type text}, {"Column10", type text}, {"Column11", type text}, {"Column12", type text}, {"Column13", type text}, {"Column14", type text}, {"Column15", type text}, {"Column16", type text}, {"Column17", type text}}), 
    #"Promoted Headers" = Table.PromoteHeaders(#"Changed Type"), 
    //Create List of week dates  
    MondayInWeekStep1 = Table.ColumnNames(#"Promoted Headers"), 
    MondayInWeekStep2 = List.Skip(MondayInWeekStep1,4), 
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Promoted Headers", {"Name", "Client", "Type", "Key"}, "MondayInWeek", "Staff Hours"), 
    ReOrganizedTable = Table.TransformColumnTypes(#"Unpivoted Columns",{{"MondayInWeek", type date}, {"Staff Hours", Int64.Type}}), 
    AddFilenameColumn= Table.AddColumn(ReOrganizedTable, "FileName", each CurrentFilename) 
in 
    AddFilenameColumn, 
    ListOfTables = List.Transform(FileNameListStep1, (filename) => IterationFunction(filename)), 
    #"Converted to Table" = Table.FromList(ListOfTables, Splitter.SplitByNothing(), null, null, ExtraValues.Error), 
    #"Expanded Column1" = Table.ExpandTableColumn(#"Converted to Table", "Column1", {"Name", "Client", "Type", "Key", "MondayInWeek", "Staff Hours", "FileName"}, {"Name", "Client", "Type", "EmployeeNr", "MondayInWeek", "Staff Hours", "FileName"}) 
in 
#"Expanded Column1" 

Answer 1

IT는 IterationFunction

#"Custom Data1" = #"Filtered Rows"{0}[Custom.Data], 

의 3 선이되어야한다고 나에게 같습니다

을했다

#"Custom Data1" = FilterOneDataSetAtATime{0}[Custom.Data],
