Explanation

Calculated fields in Splunk are a type of knowledge object that apply an eval expression to existing fields at search time to produce a new field. They must be based on fields that already exist in the event data-specifically extracted fields (fields parsed from the raw event text). They cannot be based on tags, lookup output fields, or fields generated dynamically within a search string, because calculated fields are evaluated before those mechanisms apply.
