When you use a mapplet in a mapping, you use an instance of the mapplet. Any change made to the mapplet is inherited by all instances of the mapplet. Mapplets can contain other mapplets. You can also use a mapplet more than one time in a mapping or mapplet. You can create a mapplet manually. You can also generate a mapplet from a segment within a mapping or mapplet.

For more information about mapplets, see Mapplets.
