Understanding Dependency Types

When you propagate port attributes, the Designer can update the following dependencies:

Link path dependencies.
A link path dependency is a dependency between a propagated port and the ports in its link path. When you propagate link path dependencies, the Designer also performs default updates to references in expressions and conditions that depend on ports in the link path.

Implicit dependencies.
An implicit dependency is a dependency within a transformation between two ports based on an expression or condition.

For example, when you change the datatype of a port that is used in a lookup condition, the Designer propagates the datatype change to the other port dependent on the condition.
