Plant Editing is the ability to use the Engineering Data Editor to manage data for all objects in the plant. If System Editing is enabled, data that is edited will propagate according to the System Editing rules defined for the plant.
Plant Editing of Objects in Non-Active Drawings
If a user edits an object in a non-active drawing, propagation of data takes place across Off-Page Connectors (OPCs) to other non-active drawings when all the drawings involved are not opened by a user.
Plant Editing of Objects in an Active Drawing
If a user edits an object in the active drawing, data will not propagate across OPCs beyond the active drawing boundary. Because the active drawing opened by the user is in a locked state, any data changes made in a non-active drawing will not propagate back across OPCs to the active drawing.
