A value of True for TraceIndeterminateFlow specifies that features with indeterminate or uninitialized flow will be traced by directional trace tasks. A value of False specifies that only features with determinate flow direction can be traced.
Remarks
Directed trace tasks use the flow direction on network features to determine whether or not the feature is included in the results of a trace operation. For example, the Trace Upstream trace task includes only features which are traced against their flow direction.
