Lookup % Rebate on another table based on Invoice quantity

Hi,


I want to get the correct % Rebate from table A into table B based on the Invoice Qty of each Customer. 

How can I get it done via power query?

Table A

Table B

try this

Custom1 = 
        Table.AddColumn(
            Data,
            "Rebate",
            each
                List.Select( 
                    Table.ToRows( Table.ReverseRows( Rebate ) ), 
                    (x)=> x{0} = [Year Channel] and x{1} <= [Invoice Qty] 
                ){0}?{2}? ?? 0
        )

Hi Kirete,

 

Still get the same result, duplicating the records for each customer code with different %Rebate

NewStep=let a=Table.Buffer(Table.Group(TableA,"Key",{"n",Table.ToRows})) in Table.AddColumn(TableB,"%Rebate",each let lst=a{[Key=[Year_Chaneel]]}?[n]? in if lst=null then 0 else List.Last(List.RemoveLastN(lst,(x)=>x{1}>[Invoice Qty]),{}){2}? ??0)

Hi Daniel,

 

Thanks for your reply.

However based on your formula each Customer Code got duplicate into many lines with different %Rebate

what's the relationship between those two tables? does one table comes from the other?

It is a many to many relationship between these 2 tables applied.
