No matter how many Omniture Support people tell you that there is no limit on the number of characters you can use as your serial number when implementing Event Serialization, they are wrong!

The limit is 20 characters.

It took me 3 phone calls and a weeks worth of bad data to figure that out. It is no where to be found in their white papers either, so don’t bother looking there.
