When adding a network rule, no valid asset type was found for the asset group.
Many configuration tasks rely on a classification system built into the feature class schema using the asset group and asset type attribute fields. The asset type field requires a valid attribute domain to be created and assigned to represent the minor classification of assets.
Certain rule types require that an association role is assigned to support the rule. See the following workflows if you are creating containment or structural attachment rules:
Ensure that valid attribute domains are created and assigned to the asset type field at the asset group (or subtype) level.
- See Configure a utility network and View and edit subtypes in the Subtypes view for information on assigning attribute domains to fields for specific subtypes.
Ensure that the appropriate association role assignments are made before creating structural attachment and containment rule types.
