Excel Facts

Last used cell?

Please try

1 NestedJoin
Power Query:
let
    Source = Table.Buffer(Excel.CurrentWorkbook(){[Name="Table1"]}[Content]),
    MergedQueries = Table.NestedJoin(Source, {"BRAND", "SAC"}, Table1, {"BRAND", "SAC"}, "Table1", JoinKind.LeftOuter),
    Last = Table.AddColumn(MergedQueries, "Last", each Table.Last(Table.SelectRows([Table1], (x)=> x[DATE] < [DATE]))),
    ExpLast = Table.ExpandRecordColumn(Last, "Last", {"DATE", "ITEMDISCPC"}, {"C_DATE", "C_ITEMDISCPC"}),
    AStatus = Table.AddColumn(ExpLast, "C_Status", each if [C_ITEMDISCPC] = null then null else if [C_ITEMDISCPC]=[ITEMDISCPC] then "s" else "ns")
in
    AStatus

2 SelectRows
Power Query:
let
    Source = Table.Buffer(Excel.CurrentWorkbook(){[Name="Table1"]}[Content]),
    Latest = Table.AddColumn(Source, "Last", each    Table.Last(Table.SelectRows(Source, (s)=> s[SAC]=[SAC] and s[BRAND]=[BRAND] and s[DATE]<[DATE] ) )),
    ExpLast = Table.ExpandRecordColumn(Latest, "Last", {"DATE", "ITEMDISCPC"}, {"C_DATE", "C_ITEMDISCPC"}),
    AStatus = Table.AddColumn(ExpLast, "C_Status", each if [C_ITEMDISCPC] = null then null else if [C_ITEMDISCPC]=[ITEMDISCPC] then "s" else "ns")
in
    AStatus

Not sure which one is faster, my guess is NestedJoin.

Dear Mr. Bo_Ry ,
