Role required: Scan Engine admin \(sn\_se.scan\_engine\_admin\)

This task sets the exception reason options in order. For what each setting does and the values it accepts, see [Configure exception reason properties](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/impact/exception-reason-properties.md). For an overview of exception reasons and the approval lifecycle, see [Exception handling in Scan Engine](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/impact/exception-handling-overview.md).
