Hello

I cannot figure out how to get new columns into my Power Query if the data source changes.

I import multiple CSV files from a specific folder using Get Data -> From File -> From Folder option

Recently CSV files have been amended where couple additional columns were added at the end. Unfortunately my import query doesnt pick-up new columns at all.

I am desperate to get them asap but would like to avoid option where I have to redo the whole query from scratch.

Please help :biggrin:

Code:
let    Source = Folder.Files("\\XXX\Data"),
    #"Filtered Hidden Files1" = Table.SelectRows(Source, each [Attributes]?[Hidden]? <> true),
    #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from Sales Orders Report (2)", each #"Transform File from Sales Orders Report (2)"([Content])),
    #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from Sales Orders Report (2)"}),
    #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from Sales Orders Report (2)", Table.ColumnNames(#"Transform File from Sales Orders Report (2)"(#"Sample File (3)"))),
    #"Renamed Columns" = Table.RenameColumns(#"Expanded Table Column1",{{"SalesID", "Order Number"}, {"SalesOrigin", "Origin"}, {"HeaderCreatedDateTime", "Order Date"}, {"DeliveryDate", "RDD"}, {"CustomerAccountNumber", "Customer Account"}, {"CustomerName", "Customer Name"}, {"InvoiceAccountNumber", "Invoice Account"}, {"InvoiceAccountName", "Invoice Account Name"}, {"channel", "Channel"}, {"Sales_Channel", "Sales Channel"}, {"salessubchannel", "Sales Sub Channel"}, {"accountmanager", "Account Manager"}, {"InventorySite", "Inventory Site"}, {"Order_Status", "Order Status"}, {"WAXReleaseStatus", "Release Status"}, {"DocumentStatus", "Document Status"}, {"DeliveryMode", "Delivery Mode"}, {"LineNumber", "Line Number"}, {"Line_Status", "Line Status"}, {"ItemID", "Item"}, {"ItemName", "Item Description"}, {"subcategory1", "Cat 1"}, {"subcategory2", "Cat 2"}, {"ReportingGroup", "Reporting Group"}, {"QTYOrdered", "Ordered Qty"}, {"Delivered_Qty", "Delivered Qty"}, {"SalesUnit", "Unit"}, {"SalesPrice", "Sales Price"}, {"Line_Amount_GBP", "Line Amount GBP"}, {"Line_Amount_Curr", "Line Amount Curr"}, {"CurrencyCode", "Currency Code"}, {"CustomerPurchaseOrderNumber", "Customer Order Number"}, {"Hdr_Time", "Order Time"}, {"CreatedBy", "User ID"}, {"CreatedByName", "User Name"}, {"FSCreditBlocked", "Credit Hold"}, {"SalesType", "Sales Type"}, {"payment", "Payment Terms"}}),
    #"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"Order Date", type date}, {"RDD", type date}, {"Ordered Qty", type number}, {"Delivered Qty", type number}, {"Sales Price", type number}, {"Line Amount GBP", type number}, {"Line Amount Curr", type number}, {"Order Time", type time}}),
    #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([Origin] <> "Debit Note")),
    #"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", each [Category] <> "Service")
in
    #"Filtered Rows1"
