Add Network Attribute (Trace Network)

Summary

Adds a network attribute to a trace network.

Usage

• A network attribute can be associated with only one attribute on a feature class; however, it can be associated with multiple feature classes.

• The network topology must be disabled.

• This tool can be used with the Set Network Attribute tool, which is used to assign the network attribute to a feature class field in the trace network.

• When working with an enterprise geodatabase, the requirements are as follows:

  • The input trace network must be from a database connection established as the database trace network owner.

  • License:

    The active portal account must be licensed with the ArcGIS Trace Network user type extension to create, publish, and work with a trace network in an enterprise geodatabase.
  • This tool must be executed when connected to the default version.
