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.
