Sales Order hold

From reading this thread (credit-hold) it seems that B1 has the ability to automatically place a sales order on hold if it exceeds the customers credit limit. I have entered numerous sales orders in the test company exceeding the credit limits of a customer, but none of the sales orders seemed to go on "HOLD" status as I was able to convert them to deliveries and invoices.

Is there something in the comany setup that needs to be marked to activate the automatic hold?

Also, can a password be created to override the "exceed customer credit limit" warning. Right now warning can be simply overriden by clicking continue.
