Enable Topology


Enabling the network topology for a utility network is done on the DEFAULT version. Enabling is not supported in named versions. When the topology is enabled, all feature and association edits generate dirty areas, which are then consumed when you use validate to update the network topology. When the topology is enabled, the following happens:

  • The topology is updated for the full extent of the network.
  • All errors are deleted.
  • Any new errors are added to the dirty areas sublayer.
  • The topology is marked as enabled.

Enabling the topology is supported both synchronously and asynchronously. While the network is being enabled, all other sessions connected to the DEFAULT version are blocked from running validate or enable operations.

The active portal account must be assigned a license with the ArcGIS Advanced Editing user type extension to use this operation.
