The Rule option allows you to attach a rule to an element. There are three options on the Rules submenu—Prior, Post, and Remove. Prior rules are performed before the element is mapped, and Post rules are performed after the element is mapped. Use Remove to remove a rule that was previously attached to the element. Post rules are generally used for inbound maps.
On outbound transaction maps, rules attached to an element
are not performed if the field that is mapped to the element does
not contain data.
