Lookup based on multiple criteria

Hi Guys,   I need help on how to lookup using multiple criteria. I need to update the "Status" of Sheet1 based on the criteria from Sheet2. The criteria is if the employee falls on a specific date ...

    You can add a column in the query editor that checks the conditions like this:

     

    Table.SelectRows(Sheet2, (Sheet2) => Sheet2[START DATE]<=[Date] and Sheet2[STOP DATE] >= [Date] and Sheet2[ID]=[ID])[Status]{0}

    If this is too slow, you have  to use a function like this:

     

    (Table1 as table, DateColumn1 as text, ListJoinColumns1, TableLookup as table, DateFrom as text, DateUntil as text, ListJoinColumns2, LookupField as text) =>

let
    #"Merged Queries" = Table.NestedJoin(Table1,ListJoinColumns1,TableLookup,ListJoinColumns2,"Lookup",JoinKind.LeftOuter),
    #"Added Custom" = Table.AddColumn(#"Merged Queries", "Custom", each Record.Field(Table.SelectRows([Lookup], (Lookup) => Record.Field(Lookup, DateFrom)<=Record.Field(_, DateColumn1) and Record.Field(Lookup, DateUntil)>=Record.Field(_, DateColumn1)){0}, LookupField)),
    Result = Table.RemoveColumns(#"Added Custom", {"Lookup"})
in
    Result

    name it "fnEventDurationMultiple" and you can invoke it like this:

     

    fnEventDurationMultiple(Sheet1, "Date", {"ID"}, Sheet2, "START DATE", "STOP DATE", {"ID"}, "Status")
