1. If a flat was created by mistake and a receipt was posted against it, it can never be deleted ( otherwise there will be a missing receipt in the sequence ). In such cases, you must deactivate the flat.
2. The unit cannot be deleted if any user is assigned to it, so make sure there are no users assigned to it before deleting it.
3. Ensure that there is no active financial data against the unit (if there is, the unit cannot be deleted).
