Using Mapplets in Mappings

Using Mapplets in Mappings

In a mapping, a mapplet has input and output ports that you can connect to other transformations in the mapping. You do not have to connect all mapplet ports in a mapping. However, if the mapplet contains an SQL override, you must connect all mapplet output ports in the mapping.
Like a reusable transformation, when you drag a mapplet into a mapping, the Designer creates an instance of the mapplet. You can enter comments for the instance of the mapplet in the mapping. You cannot otherwise edit the mapplet in the Mapping Designer.
If you edit the mapplet in the Mapplet Designer, each instance of the mapplet inherits the changes.
The PowerCenter Repository Reports has a Mapplets list report that you use to view all mappings using a particular mapplet.
To use a mapplet, complete the following steps:
  1. Drag the mapplet into the mapping.
  2. If the mapplet contains input ports, connect at least one mapplet input port to a transformation in the mapping.
  3. Connect at least one mapplet output port to a transformation in the mapping.
