Creates a CLUSTERKEY attribute field on classes in utility network versions 4 through 7. This attribute field is updated by the Calculate Cluster Keys tool with values that facilitate the grouping of features and objects in the network topology.
Cluster keys enable analytical operations to be performed more efficiently in the utility network when working with nonspatial junction and edge objects. The cluster keys are consumed by the network topology on enable and can be helpful when running operations that query the network topology, such as a trace.

The network topology must be disabled.
When working with an enterprise geodatabase, the Input Utility Network parameter value must be from a database connection established as the database utility network owner.
An exclusive lock must be obtained, meaning that you must close active connections to the dataset, including those from services.
