Updating an Employee record in HEAT Premise Service Management 2014.x produces the error message.
Error while saving data: View or function 'Employee' is not updatable because the modification affects multiple base tables.
This usually occurs after the Employee view is dropped and recreated/restored in SQL from a backup or from a Staging or other tenant running the same configuration.
Frontrange Support recommends that you back up the Production database before executing the scripts.
The triggers must be scripted from a source database which contains precisely the same table/column configuration as the target, otherwise the triggers may not be accurate.
