Description
When calculating network locations for a feature class using the Calculate Locations tool, if the input has a CurbApproach field, the values in this field may be used to influence locating behavior. However, if the values in this field don't match one of the valid domain values for CurbApproach (0, 1, 2, 3), the field value for that row will be ignored when locating the point and the default value of 0 will be used.
Solution
Correct the invalid values in the CurbApproach field or ignore the warning if the default behavior is acceptable.
