I am trying to calculate geometry for a set of polygons and find their area. At first I was getting an error that said "Failed to apply changes after updating the row with objectID=0 with the calculated value" and it would only give me 5 areas out of 39. Then I hit start editing and tried again and this time values populate but it wont let me save them due to a row error. Any guidance is appreciated because I don't know what could be wrong with my rows.
Try your calculate geometry outside of your edit session.
You should run a Repair Geometry tool when you are done editing and before any calculations as well
