Does EVO have a verification check on the packing slip number entered in PO-C (receiving purchase orders) to prevent duplicate entry of same packing slip number?
 
(Similar to Account Payable, when one enters a invoice number, EVO will respond if that invoice number has already been used/entered).
 
Reason for my question, is that recently our receiving department entered duplicate receipts for 4 packing slips.  They recevied the duplicated shipment entries against future date releases on the same purchase order.   Granted, receiving is not very smart, but if we start entering the packing slip number into EVO, I was just wondering if this kind of check would prevent duplication.  

Thanks for the quick response!
