7.3.1 About Operational Content IDs, node IDs, and Guide Part IDs
A specific ID is automatically assigned to each of Operational Content, nodes, and parts when they are created. You can change node IDs and Guide Part IDs in the Attribute Settings window, but Operational Content IDs are fixed.
If you want to directly display a specific Operational Content, you need the Operational Content ID. In addition, Operational Content IDs and node IDs are used in operation logs for analyzing the Operational Content execution log. To use drop-down parts having parent-child relationship, you need Guide Part IDs.
Note that the nodes and Guide Parts in the same area must have unique IDs.
