I'm trying to use our CCTV data with the CCTV Manager. It works however the televised mains layer produces NULL values for all the existing fields, including most importantly Flow. I've tried using both "U" and "Upstream". I know I could easily join the data to the original tale based on inspection but seems like this should work. Any suggestions or anyone else experience this? We are using a custom schema. ArcGIS Pro 2.2.1.
