Calculate Function inside custom column Power Query

[beckmansuccess]

Hello,

I am currently using a dax formula in a calculated column to complete the following Count formula.

Orders in Route = CALCULATE(COUNTA('OrderTable'[Order Number]),

FILTER('OrderTable', 'OrderTable'[Customer]='Summary'[Customer]),

FILTER('OrderTable', 'OrderTable'[Mode]='Summary'[Mode]),

FILTER('OrderTable', 'OrderTable'[Depart]<='Summary'[DateTime]),

FILTER('OrderTable', 'OrderTable'[Arrive]>='Summary'[DateTime]))

I am needing to move this to a Power Query custom column to save memory.

NewStep=Table.ReplaceValue(Table.NestedJoin(Summary,{"Customer","Mode"},OrderTable,{"Customer","Mode"},"Orders in Route",JoinKind.LeftOuter),each [DateTime],"",(x,y,z)=>if x=null then x else Table.RowCount(Table.SelectRows(x,each [Depart]<=y and [Arrive]>=y)),{"Orders in Route"})
