Duplicate Invoice No and Use Data from 2nd record

Hi Centaur ,

You're very close! The issue you're running into—"Token expected"—is due to a missing comma at the end of the previous step. In Power Query M code, each step must be separated by a comma, except for the final one before the in keyword.

In your code, you ended the RemoveHelper step like this:

RemoveHelper = Table.RemoveColumns(UpdatedGR, {"GoodsReceiptToKeep", "Goods Receipt"})

But then immediately started the next step with:

#"Removed Duplicates" = Table.Distinct(#"RemoveHelper", {"Invoice No Stripped", "Invoice amount"}),

Since "Removed Duplicates" is technically the next step after RemoveHelper, you need to put a comma at the end of the RemoveHelper line to separate the steps properly. Here’s the corrected version of that section:

RemoveHelper = Table.RemoveColumns(UpdatedGR, {"GoodsReceiptToKeep", "Goods Receipt"}),  
#"Removed Duplicates" = Table.Distinct(RemoveHelper, {"Invoice No Stripped", "Invoice amount"}),

Also, you don't need the #"" syntax for RemoveHelper unless it includes spaces or special characters—RemoveHelper works fine as a reference on its own, and using #"RemoveHelper" can sometimes cause confusion if it was never defined with quotes.

Here is what i believe would solve your issue:

let
    Source = Table.Combine({StampliALLPaid, #"Project Costs"}),

    #"Uppercased Text" = Table.TransformColumns(Source,{{"Invoice No Stripped", Text.Upper, type text}}),

    #"Reordered Columns3" = Table.ReorderColumns(#"Uppercased Text",{
        "Processing Began", "Vendor", "WDDate", "Invoice #", "Invoice No Stripped", "Source", "Invoice amount", 
        "Currency", "Invoice date", "Invoice due date", "Company Code", "Budget Category", "Invoice Status", 
        "Goods Receipt", "Project ", "Funding Date", "DDNo", "USD Amount", "Account", "TypeDraw"}),

    #"Sorted Rows" = Table.Sort(#"Reordered Columns3",{
        {"Invoice No Stripped", Order.Ascending}, 
        {"Source", Order.Ascending}}),

    GroupedRows = Table.Group(#"Sorted Rows", {"Invoice No Stripped", "Invoice amount"}, {
        {"AllData", each _, type table [
            Invoice No Stripped=nullable text, 
            Source=nullable text, 
            Invoice amount=nullable number, 
            Goods Receipt=nullable text,
            Processing Began=nullable datetime, Vendor=nullable text, WDDate=nullable date, 
            Invoice #=nullable text, Currency=nullable text, Invoice date=nullable date, 
            Invoice due date=nullable date, Company Code=nullable text, Budget Category=nullable text, 
            Invoice Status=nullable text, Project = nullable text, Funding Date=nullable date, 
            DDNo=nullable text, USD Amount=nullable number, Account=nullable text, TypeDraw=nullable text
        ]}
    }),

    AddGRColumn = Table.AddColumn(GroupedRows, "GoodsReceiptToKeep", each 
        let
            groupTable = [AllData],
            grValue = try Record.Field(
                Table.SelectRows(groupTable, each Text.Contains([Source], "Stampli")){0}, 
                "Goods Receipt"
            ) otherwise null
        in grValue
    ),

    Expanded = Table.ExpandTableColumn(AddGRColumn, "AllData", {
        "Processing Began", "Vendor", "WDDate", "Invoice #", "Invoice No Stripped", "Source", 
        "Invoice amount", "Currency", "Invoice date", "Invoice due date", "Company Code", 
        "Budget Category", "Invoice Status", "Goods Receipt", "Project ", "Funding Date", "DDNo", 
        "USD Amount", "Account", "TypeDraw"
    }),

    UpdatedGR = Table.AddColumn(Expanded, "Final Goods Receipt", each 
        if Text.Contains([Source], "1-PC") then [GoodsReceiptToKeep] else [Goods Receipt]
    ),

    RemoveHelper = Table.RemoveColumns(UpdatedGR, {"GoodsReceiptToKeep", "Goods Receipt"}),

    #"Removed Duplicates" = Table.Distinct(RemoveHelper, {"Invoice No Stripped", "Invoice amount"}),

    #"Add Column" = Table.AddColumn(#"Removed Duplicates", "Custom", each 
        if [WDDate] = null then [Invoice due date] else [WDDate]
    ),

    }),

    Custom1 = Table.AddColumn(#"Reordered Columns", "Custom2", each 
        if [Custom] = null then [Funding Date] else [Custom]
    ),

    #"Reordered Columns1" = Table.ReorderColumns(Custom1,{
        "Processing Began", "Vendor", "WDDate", "Custom2", "Custom", "Invoice #", 
        "Invoice No Stripped", "Invoice amount", "Currency", "Invoice date", "Invoice due date",

        "Funding Date", "DDNo", "USD Amount", "Account", "TypeDraw"
    }),

    #"Removed Columns" = Table.RemoveColumns(#"Reordered Columns1",{"WDDate", "Custom"}),

    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom2", "WDDate"}}),

    #"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"WDDate", type date}}),

    #"Reordered Columns2" = Table.ReorderColumns(#"Changed Type",{
