How to fill attribute field of one feature based on calculation on attribute field of another feature and relate them so data gets updated when edited in the other feature class?

Hey folks,

I was wondering if it is possible to calculate a field in one feature class based on attributes in another feature class, and relate them so when I edit in my second feature class the calculated field in my first feature class gets updated automatically?

Thank you.

Not an expert in that area but I think you'll need to use a database trigger of some sort.  That link is specific to SQL Server, so find the relevant docs for whatever DBMS you're using.

Thank you  I will try and look more into it to see if that could be a solution.

Hi Niklas,

I would recommend looking at the attribute assistant tool for ArcMap. You are able to run rules with the attributes and two of them are to calculate field based upon intersecting feature and the other is to update intersecting feature. There is plenty of documentation here.

Thanks, I will consider it if another case appear with same problem.
