Mapplets and Mappings

Mapplets and Mappings

The following mappings tasks can also be performed on mapplets:
  • Set tracing level.
    You can set the tracing level on individual transformations within a mapplet in the same manner as in a mapping.
  • Copy mapplet.
    You can copy a mapplet from one folder to another as you would any other repository object. After you copy the mapplet, it appears in the Mapplets node of the new folder.
    If you make changes to a mapplet, but you do not want to overwrite the original mapplet, you can make a copy of the mapplet by clicking Mapplets > Copy As.
  • Export and import mapplets.
    You can export a mapplet to an XML file or import a mapplet from an XML file through the Designer. You might want to use the export and import feature to copy a mapplet to another repository.
  • Delete mapplets.
    When you delete a mapplet, you delete all instances of the mapplet. This invalidates each mapping containing an instance of the mapplet or a shortcut to the mapplet.
  • Compare mapplets.
    You can compare two mapplets to find differences between them. For example, if you have mapplets with the same name in different folders, you can compare them to see if they differ.
  • Compare instances within a mapplet.
    You can compare instances in a mapplet to see if they contain similar attributes. For example, you can compare a source instance with another source instance, or a transformation with another transformation. You compare instances within a mapplet in the same way you compare instances within a mapping.
  • Create shortcuts to mapplets.
    You can create a shortcut to a mapplet if the mapplet is in a shared folder. When you use a shortcut to a mapplet in a mapping, the shortcut inherits any changes you might make to the mapplet. However, these changes might not appear until the Integration Service runs the workflow using the shortcut. Therefore, only use a shortcut to a mapplet when you do not expect to edit the mapplet.
  • Add a description.
    You can add a description to the mapplet in the Mapplet Designer in the same manner as in a mapping. You can also add a description to the mapplet instance in a mapping. When you add a description, you can also create links to documentation files. The links must be a valid URL or file path to reference the business documentation.
  • View links to a port.
    You can view links to a port in a mapplet in the same way you would view links to a port in a mapping. You can view the forward path, the backward path, or both paths.
  • Propagate port attributes.
    You can propagate port attributes in a mapplet in the same way you would propagate port attributes in a mapping. You can propagate attributes forward, backward, or in both directions.
