How do you stop sales orgs from Voiding agreements?
Company admins in the installer's account can enable a setting to disallow sales orgs from voiding contracts.
Click My Roles > EPC > Sales Org and click settings next to the sales org you want to edit.
On the left hand side bar, click agreements.
Toggle on the setting "Turn on Void Agreement Privileges by Role."
When toggled on, an admin can select which roles are allowed to void agreements. Users with admin permissions will always be able to void agreements. This setting is set at a sales org level and would need to be enabled/disabled for each org.
