Error Creating Job Sales Invoices for cust with a bill-to

kar100

Getting an error message trying to create a sales invoice from a Job when the bill-to customer is set on the customer:
"Bill-to Customer must be equal to '' in Customer".
Anyone know the reason for this validation?
Don't see why we shouldn't be able to create a Job Sales Invoice with a different bill-to customer to the the sell-to customer no.
