Changes to certain tables must be audited. If the Run business rules option on the Transform Map record is cleared, changes made by that transform map are not audited.
Affects all Enterprise versions and environments. (Transform maps are not used in Business Edition.)
This is expected behavior. The Run business rules option on the transform map effectively runs GlideRecord.setWorkflow(false). Clearing the Run business rules option stops all auditing, business rules, workflows, approval engines, field normalizations, and other processes during a transform. For a complete list of scripts and engines that do not run when this field is cleared, see Execution Order of Scripts and Engines.
To audit all changes made by a transform map, ensure that the Run business rules option is selected.
