Some Informatica Platform transformations contain separate input and output ports. For most transformations that have separate input and output ports, Metadata Manager can determine the data lineage links between the input ports and the output ports.
Transformations such as Aggregator, Expression, Joiner, and Union transformations can contain separate input and output ports. Metadata Manager can determine the data lineage links between the input and output ports in these transformations. Data lineage links between input and output ports in the same transformation are called port-to-port data lineage links.
The following image shows port-to-port data lineage links within a Union transformation:
Metadata Manager can determine port-to-port data lineage for the following transformations that have separate input and output ports:
Address Validator
Aggregator
Association
Case Converter
Classifier
Comparison
Consolidation
Decision
Exception
Expression
Joiner
Key Generator
Labeler
Match
Merge
Parser
Rank
Router
Standardizer
Union
Weighted Average
Metadata Manager cannot determine port-to-port data lineage for other transformations that have separate input and output ports. When Metadata Manager cannot determine port-to-port data lineage for a transformation, it maps all input ports to all output ports within the transformation.
