At universal containers some Manufacturing cloud users have ‘Delete sales agreement’ profile permission.

According to the Salesforce Manufacturing Cloud documentation, the ‘Delete sales agreement’ profile permission allows users to delete an active, approved, canceled, or expired sales agreement. However, they can only delete a sales agreement if it doesn’t have any active orders associated with it. Only users with this permission will see the ‘Delete’ option on the sales agreement record header. Account owners or other users without this permission will not see the ‘Delete’ option. The status of the sales agreement does not affect the ability to delete it, as long as there are no active orders1. References: 1: Delete a Sales Agreement - Salesforce
