Bar codes are an essential part of every company, and the method of use can be different from company to company. Given this situation, SAP Business One allows you to define multiple bar codes for each unit of measure and each item.
Go toInventory > Bar Codes. Here you may have multiple bar codes for each unit of measure and each item. You can also set a default. You may change the bar code in this document if necessary. We also can select a bar code on a new document line, and the corresponding item will show up automatically.
