An audit report contains a list of changed and deleted lines in the source files (including copybooks) from which a logical component was extracted. The report has a name of the form <component>.audit.txt. Click the report in the Components tab to view its text.
An audit report optionally includes reason codes explaining why a line was changed or deleted. A reason code is a number keyed to the explanation for a change (for example, reason code 12 for computation-based componentization is RemoveUnusedVALUEs).
