This is a common use case that can be easily accomplished in CFLOW. Lets assume that the serial code is constructed as follows – a constant ‘CA’ to denote the company name, first two letters of the product, month and year of this submission and a 4-digit auto-increment number. This can be designed using the String concatenation feature as shown below –

You will first create a hidden field that has all the concatenations configured and then add another field setup for appending the auto-increment number to the concatenated id.
Try it out and let us know how it works out for you.
