This results in having the right product with the right quantity shipped but with serialization data missing for some of the product packages where the supplying site missed to scan. If the packages with the missing serial numbers are at the saleable unit level that is inside a case, then wholesaler’s system may not catch this until at the time of their downstream pick/pack process.
Add a system control at the manufacturer/3PL shipping process to automatically compare the total number of serial numbers scanned for the order to the total quantity of the order and make sure they match. And if there is a mismatch, throw an error message and stop the transaction in the system. The same kind of process need to be established at the wholesaler receiving process where there should be an automatic check to see if the number of serial numbers received in the TI matches with the total physical quantity received.
