Description
The StreamLink field could not be determined, and it was not added as a field in the output feature class attribute table. This is because the output features correspond to multiple stream segments, not individual segments. A unique ID, which is used to populate the StreamLink field in the output feature class attribute table, can only be assigned to stream segments.
Solution
Do one of the following:
- Keep the Group By Field parameter set to its default value, which is NONE.
- Ensure that the values in the field selected for the Group By Field parameter value are unique for each stream segment.
