When working in OPPID and in OPM. You can create a pipeline where an Associated Item has <None> set as the value. Assuming the Associated Item you are setting is in the Name property expression for Pipeline.

When user selects <None> In OPPID it will create the pipeline but will not sync to PlantSight. In OPM when the user sets the Associated Item property to <None>; they can't create the pipeline at all. The Name property fails and the line is never created.

By adding a default value of "Undefined" (or similar) a user can use that value in both OPPID and OPM and be able to sync to PlantSIght in OPPID and create the line in OPM without errors.
