    Matt_JEM Try with:

    let
    // Step 1: Connect to SQL Database and Load Table
    Source = Sql.Databases("jt-sysprosqlsvr"),
    SysproCompanyJEM = Source{[Name="SysproCompanyJEM"]}[Data],
    dbo_QotMaster = SysproCompanyJEM{[Schema="dbo", Item="QotMaster"]}[Data],

    // Step 2: Sort data by Quote (ascending) and QuoteVersion (descending) so the highest version appears first
    SortedData = Table.Sort(dbo_QotMaster, {{"Quote", Order.Ascending}, {"QuoteVersion", Order.Descending}}),

    // Step 3: Group by Quote, keeping only the first row (which now has the highest QuoteVersion)
    GroupedData = Table.Group(SortedData, {"Quote"}, {{"AllData", each Table.FirstN(_, 1), type table [Quote=nullable text, QuoteVersion=nullable number, QuoteStatus=nullable text]}}),

    // Step 4: Expand the grouped table, but exclude the duplicated "Quote" column
    ExpandedData = Table.ExpandTableColumn(GroupedData, "AllData", {"QuoteVersion", "QuoteStatus"})

    in
    ExpandedData

     

    can you paste a sample data on which work in parallel?

Hi Matt_JEM, check this:

 

Before

 

After

 

Replace word GroupKind.Local with GroupKind.Global in code if your [Quote] column is not sorted in the table, but keep it if it is. Do not sort it as a separate step - it is not necessary.

let
    Source = Table.FromColumns({{"0001", "0001", "0002", "0003", "0004", "0004"}, {0,1,0,0,1,0}}, {"Quote", "QuoteVersion"}),
    FilteredMaxQuoteVersion = Table.Combine(Table.Group(Source, {"Quote"}, {{"T", each Table.MaxN(_, {"QuoteVersion"}, 1), type table, GroupKind.Local}})[T])
in
    FilteredMaxQuoteVersion
