Here is the Answer from our Quality Dept:
Setting up a batch protocol is a simple process.
They can set it up to what can give them the most information regarding the product that has that number assigned.
For us, we make use of our Sales order number which contains all the information regarding the order.
We lead with a number to represent the year. Other places I worked at used and a letter to represent the year followed by the Julian day to help identify the day it was made followed by 01, 02 to indicate the number of the batch of the day. You want each “code” to be unique to each product. Hopefully, this will help.
