What is a requirement for running a trace in a subnetwork?

For conducting a trace in a subnetwork, it is essential that there are no dirty areas present. Dirty areas are defined as regions within the geodatabase that contain inconsistencies or errors in the spatial or attribute data, which can negatively impact the integrity and accuracy of network analysis.

When a trace is performed, it relies on a clean and consistent dataset to function correctly. If dirty areas exist, they could lead to inaccurate results or even prevent the trace from being executed effectively, as the tracing process requires a reliable assessment of connectivity and relationships within the network. By ensuring that there are no dirty areas, the data integrity is maintained, enabling reliable tracing operations within the subnetwork.

Other options may involve necessary conditions for specific scenarios within the utility network framework, but the absence of dirty areas stands out as a fundamental requirement for the accuracy and success of the tracing process.
