We have 2 options: we have dormant (only BS balances but remain constant) or inactive (no balances/activity). For both of these we move them to an WF profile for entities that dont have inputs (wish this could be based on an effective date) and set write access to admin only. Then for dormant entities we have a business rule that copies the balances over each month since they never change (selection based on entities that have a specific value in a text field with effective date). Then for inactive entities set the in-use flag to false with effective date.
