Automatic Check of Duplicate Cust. Ref. No.'s in a Sales Order

Question

Hi Everybody,
Does anybody know how to enable SAP B1 to automatically check if a Cust. Ref. No. has already been assigned to another sales order?  This seems like a basic function, but I can't seem to find it.  I checked under Document Settings, General Settings and Company Settings.
Thank you in advance,
Amanda
