Pseudo links
The Integration Flow Designer automatically derives external links and displays them using solid directed lines. The Integration Flow Designer also enables you to manually define external links between two components. These are called pseudo links. A pseudo link is displayed using a dotted directed line.
Pseudo links represent data flow relationships that cannot be derived statically at design time. They help you to visualize data flow relationships that are established at execution time. The Integration Flow Designer does not embed pseudo links that you define into the process control information, which drives Command or Launchers. Pseudo links serve a visual purpose only.
