We have a web service that creates/updates accounts in Salesforce. We're seeing different behavior between Production and Sandbox with the enforcement of the length of Billing City. In Production the create/update fails if the new Billing City value is longer than 40 characters, but it doesn't fail in Sandbox; it just truncates the value to 40 characters. Can someone please explain why there's a difference between what is done on Production and Sandbox? (BTW there isn't any account validation rule ion either environment that enforces the Billing City length.)
