Openprise does not allow you to delete records directly, so you should use the native delete feature in your system. Using Openprise to identify records to be deleted can easily be accomplished by setting a field's contents to a known value and then using the system's native functionality to filter on those records and then delete them. For example, in Salesforce, you can set Lead Status = Delete and then use the bulk delete feature on the Leads object to delete all leads with status = Delete.
