    Feeder Manager and ArcMap Network Fields

    Melia Brush

      ArcMap network traces require two special-purpose fields on all network features, in order to determine how flow (electricity, water, gas, light, etc.) should behave upon reaching the feature:


          Enabled (yes/no): Whether the feature is currently functioning (and therefore allows flow across it)


          Ancillary Role (source/sink): Whether the feature operates as beginning point (source) for flow, or as an end point (sink) for flow.


      For ArcMap traces (e.g. Find Common Ancestor) to produce accurate results, any working features in a network should have Enabled set to "yes", and any features that are the starting points for the flow should have Ancillary Role set to "source."  Normally, just indicating all the sources is sufficient; you do not need to mark all the sinks. 


      ArcFM's Feeder Manager conducts its own analysis of the network, and so does not use either of these fields. 


      However, if you are already setting the Enabled field to "no"  to mark non-functioning features, and want Feeder Manager to treat those non-functioning features as end points, then as an administrator you can check the Respect Enabled field when tracing setting in ArcCatalog (see http://resources.arcfmsolution.com/10.2%20and%2010.2.1/DesktopConfig/Feeder_Manager_Settings.html).  Note that this setting only affects Feeder Manager 1 and 2 autoupdaters.  ArcFM Electric traces are based on Esri tracing, so they always stop at features with Enabled set to "no."  However, ArcFM Electric traces do not use the Ancillary role field, but rather rely on Feeder Manager to determine the sources.
