Creating a Mapplet

Creating a Mapplet

A mapplet can be active or passive depending on the transformations in the mapplet. Active mapplets contain one or more active transformations. Passive mapplets contain only passive transformations. When you use a mapplet in a mapping, all transformation rules apply to the mapplet depending on the mapplet type. For example, as with an active transformation, you cannot concatenate data from an active mapplet with a different pipeline.
Use the following rules and guidelines when you add transformations to a mapplet:
  • If you use a Sequence Generator transformation, you must use a reusable Sequence Generator transformation.
  • If you use a Stored Procedure transformation, you must configure the Stored Procedure Type to be
    Normal
    .
  • You cannot include PowerMart 3.5-style LOOKUP functions in a mapplet.
  • You cannot include the following objects in a mapplet:
    • Normalizer transformations
    • COBOL sources
    • XML Source Qualifier transformations
    • XML sources
    • Target definitions
    • Other mapplets
Although reusable transformations and shortcuts in a mapplet can be used, to protect the validity of the mapplet, use a copy of a transformation instead. Reusable transformations and shortcuts inherit changes to their original transformations. This might invalidate the mapplet and the mappings that use the mapplet.
