A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
You run a search that computes a ratio with eval on each result and then reference that ratio further down the pipeline. Where does the computed value end up?
Correct.
Checked against help.splunk.com, August 2026Concept
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 B
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.

Splunk Docs: eval command, checked August 2026The 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.
