You can define master data entries to indicate containership by assigning one or more master data entries as children of a parent (containing) master data entry. For example, if a loading dock contains two portals, you can define a master data entry for "South Loading Dock" with the children "Portal One" and "Portal Two."
See Create master data entries.
Note: A master data entry can be a child to more than one parent master data entries. It can also be tracked individually, like any other master data entry.
Note: You can remove a master data entry as a child without deleting the entry itself. See Remove child master data entries.
