Let's consider a customer order where some items have serial numbers (e.g. a TV) and some do not (e.g. cables). When we automatically generate a warehouse release document from this order, a message will appear indicating that serial numbers need to be completed.
If we click yes, we must choose which serial numbers will be issued.
It creates a Goods Issue Note with the same quantities as the Goods Receipt Note.
This process is similar when creating a Order to suppiler. We enter existing serial numbers for items, or we can generate them manually as well.
Once confirmed, a 
document is automatically created.
