Active and passive PowerCenter mapplets

Active and passive PowerCenter mapplets

Mapplets are either active or passive.
When you upload a PowerCenter mapplet in
Data Integration
, you specify whether the mapplet is active or passive.
An active mapplet includes at least one active PowerCenter transformation. An active mapplet can return a number of rows different from the number of source rows passed to the mapplet. For example, an active mapplet might aggregate five source rows and return one row.
A passive mapplet includes only passive PowerCenter transformations. A passive mapplet returns the same number of rows that are passed from the source.
