Concept

Deriving a value is only useful if something downstream can read it, so the result becomes an ordinary field. From that point it behaves like any field the data arrived with.

Why C

Splunk states that the eval command calculates an expression and puts the resulting value into a search results field, adding a new field where the name does not already exist.

Source

The eval command calculates an expression and puts the resulting value into a search results field. If the field name that you specify does not match a field in the output, a new field is added to the search results.
