A finished good can also be serialized.
After you create the Work Order and receive the Finished Good Quantity, you need to define the Serial Numbers of the new manufactured products.
To do this, go to Gear Icon > Products and click the Serial Number icon next to the product you wish to add serial numbers for:
Then, you can add the Serial Numbers of the items you just manufactured in the Location you received the Goods.
At this point, the manufactured quantity has received the new Serial Numbers and you can add these items to documents.
Note it is not yet possible to have a Work Order with both the components/raw materials and the finished good being serialized.
