Moving rules up and down in the list

Barcodes are validated against each rule in turn until a match is found, so you should list the more precise rules before general ones. In the simple example below you can see we’ve listed the AV rule before the A rule. If A came before AV then the AV rule would never be used since we’d always find a match on A.

Name	Leading characters	Trailing characters
AV rule	A	V
A rule	A

New rules are added to the top of the list. You can select a rule and then click Move Up or Move Down to change its position in the list.
