In assemblies, the main item receives the properties from ABE. When you select this item in the EDE, the properties it received from ABE can be viewed in the EDE or in the Properties grid.
After placement, connected items such as nozzles, pipe runs, and so forth, will have the Smart P&ID properties. If System Editing is turned on, the properties from ABE, except for Source Tag, are propagated to the connected items according to relationships and rules defined.
