The PT.20.01 Traffic Tree screen shows you all the milestones for tagged items and engineering requisitions.
Data is displayed here in a hierarchical order in a tree. This tree has the following structure:
The top level of nodes is dedicated to EML numbers available in the current project. EML numbers can be assigned to preliminary packing lists on the PT.20.21 Preliminary Packages screen and to release notes on the With Release Notes tab of the P.70.74 Packages screen. EML numbers allow for a specific evaluation in the traffic tree. Traffic objects without any relation to an EML number can be found below the top-level node 'Traffic'. If you do not have any EML numbers defined in your project and only the 'Traffic' node is available on the top level, the 'Traffic' node will be expanded automatically when you open the screen.
The work in the traffic module is split into three stages: the planned stage, the forecast stage, and the actual stage. Therefore, the three stage-level nodes below each top-level node are 'Planned', 'Forecast', and 'Actual'.
