About baselining or preliminary structures

You can release intermediate structure data for other users or suppliers to review or consume. An intermediate data release or baseline of in-progress data is sometimes called a preliminary data indicator (PDI).

You must create a baseline (PDI) of the related product structure and plant structure before you create a baseline of the process structure. This allows you to reproduce the process structure when necessary by applying the appropriate product and plant configuration rules that were applied when you created the PDI.
