Overview
The Part-Procedure Relations importer links parts to procedures, one CSV row per(part, procedure) pair. The part is identified by part_number + revision, the procedure by procedure_title + procedure_version, and the only data field is the required flag.
Re-imports are idempotent: if the link already exists, its required flag is updated to match the CSV; otherwise a new link is created.
Columns
This importer does not support custom attributes. Any column outside the list above causes a validation error.
