Viewing Mapplet Input and Output

Viewing Mapplet Input and Output

Mapplets and mapplet ports display differently in the Mapplet Designer and the Mapping Designer.
The following figure shows a mapplet with both an Input transformation and an Output transformation:
An Input transformation is connected to a series of transformations, the last of which is connected to an Expression transformation, a Filter transformation, an Update Strategy transformation, and an Output transformation. The mapplet also contains an unconnected lookup.
When you use the mapplet in a mapping, the mapplet object displays only the ports from the Input and Output transformations. These are referred to as the mapplet input and mapplet output ports.
The following figure shows the same mapplet in the Mapping Designer:
The mapplet appears as a mapplet object with input and output ports. The mapplet input is two sources and a source qualifier. The mapplet output is connected to a target.
The mapplet displays the input ports from the Input transformation. The output ports from the CODES_MAP0 Output transformation appear below the input ports.
You can expand the mapplet in the Mapping Designer by selecting it and clicking Mappings > Expand. This expands the mapplet within the mapping for view. Transformation icons within an expanded mapplet display as shaded.
You can open or iconize all the transformations in the mapplet and mapping. You cannot edit any of the properties, navigate to other folders, or save the repository while the mapplet is expanded.
The following figure shows an expanded mapplet in the Mapping Designer:
The mapplet is expanded to display its component transformations. The transformations are an Expression transformation, a Filter transformation, an Update Strategy transformation, and an unconnected lookup.
In an expanded mapping, you do not see the Input and Output transformations.
