I'm doing analysis by parts on various agricultural crops. To do so, I'm using data from county enterprise budgets to create activities and events that list the inter-industry purchases and labor required for production of each crop. Thus I'm creating a separate activity for each crop, with 16 different events representing the primary inputs. For almost all crops, 15 of the 16 event sectors remain the same, so I've been pasting them from one activity to another, and then changing the values to reflect the specific value of purchases for that crop. This works fine when all 16 of the events keep the same sectors as the previous crop, but when I change one sector to a new sector, it gives me an error (a red exclamation mark) and says "Concurrency violation: The update command affected 0 of the expected 1 records." Is this something I should be concerned about?
