Hello Omair!
Configure Field Mapping
Service Desk Field: specifies the service desk incident field to be mapped with the UIM alarm field.
CA UIM Alarm Field: specifies the alarm field for the selected service desk field.
Default Value: specifies a default value for the service desk field.
Custom value: specifies a custom value for the selected service desk field. You can specify a combination of more than one alarm field as a text string. For example, $message, $nimid, $subsys, and so on.
I believe the field that you are looking for is "affected_resource"
Kind Regards,
