In the SELECT series 5 release of Bentley OpenPlant PowerPID there is a change in the schema Custom Attributes.
Previously there was a Custom Attribute named Property Priority. This is used to set the location of the specific property within the category that is located.
In SELECT series 5 the Property Priority is no longer a separate Custom Attribute but is a variable located on the property name itself. See below.
Reference to the old Custom Attribute of Property Priority can be found in numerous How To documents in the Be Community. It will take sometime to get these updated and re-posted hence this post here.
