PowerCenter mapplets in Data Integration tasks

PowerCenter mapplets in
Data Integration
tasks

Use the following rules and guidelines for using PowerCenter mapplets in
Data Integration
tasks:
  • You can add Lookup transformations between the source and a mapplet.
  • You can add Expression transformations between the source and a mapplet, and between a mapplet and the target.
  • When you add a mapplet to a
    synchronization
    task, the
    synchronization
    task wizard removes existing field mappings. The
    synchronization
    task wizard doesn't remove existing field mappings if you add a passive mapplet between the source and target.
  • When you use an active mapplet in a
    synchronization
    task that includes a saved query, the
    synchronization
    task ignores the configured target option for the task and inserts data to the target.
  • Data Integration
    retains PowerCenter session-level overrides to the mapping.
