When you export a mapplet or you export a mapping as a mapplet, the export process creates or renames some objects in the mapplet. The export process might create Expression or Output transformations in the export XML file. The export process also renames Input and Output transformations and mapplet ports.

To generate names for Expression transformations, the export process appends characters to Input and Output transformation names. If you export a mapplet and convert targets to Output transformations, the export process combines the mapplet instance name and target name to generate the Output transformation name. When the export process renames Input transformations, Output transformations, and mapplet ports, it appends group names to the object names.

If an existing object has a long name, the exported object name might exceed the 80 character object name limit in the export XML file or in the PowerCenter repository. When an object name exceeds 80 characters, the export process fails with an internal error.

If you export a mapplet, and the export process returns an internal error, check the names of the Input transformations, Output transformations, targets, and ports. If the names are long, shorten them.
