We've released new guidelines and updated documentation for the referenceDocumentUri field in inventory adjustment mutations. By following these guidelines, your apps can maintain inventory traceability, which helps merchants troubleshoot issues and conduct audits more easily. Access the field in admin via the "Inventory adjustment changes" report in Analytics or on the Adjustment History Page.
