The export process creates an Expression transformation immediately downstream from each Input transformation and immediately upstream from each Output transformation in a mapplet. The export process names the Expression transformations as follows:

Expr_<InputOrOutputTransformationName>

The Expression transformations contain pass-through ports.

If you export a mapplet and convert targets to Output transformations, the export process creates an Output transformation for each target. The export process names the Output transformations as follows:

<MappletInstanceName>_<TargetName>

The export process names mapplet Input and Output transformations as follows:

<TransformationName>_<InputOrOutputGroupName>

The export process renames mapplet ports as follows:

<PortName>_<GroupName>
