Dax formula to get id's that not exists in other table

[Anonymous]

hello all 

I got this measure  : 

var maxDate =[max date selected]
var minDate =[min date selected]
return
CALCULATE(
[TotalCost] ,
billing[Rehesh Muchrag Flag]<>"Y",
billing[FINAL]="Y",
billing[STORNOFLAG]<>"Y",
FILTER(billing,AND(billing[IVDATE]<= maxDate ,billing[IVDATE]>= minDate )
)) 

 what i need to add to get only customer id that no exists in other table ?

 for example in sql  its  - where a.customer_id not in ( select distinct b.customer_id from other table b )

@Anonymous , Try a measure like

Measure =var maxDate =[max date selected]
var minDate =[min date selected]
var _cust = allselected(Table[Customer])
return
CALCULATE(
[TotalCost] ,
billing[Rehesh Muchrag Flag]<>"Y",
billing[FINAL]="Y",
billing[STORNOFLAG]<>"Y",
FILTER(billing,AND(billing[IVDATE]<= maxDate ,billing[IVDATE]>= minDate ) && noT(billing[Customer] in _cust )
))
