When you restore a Change Management model previously registered with SDx using the Restore one of more models from backup option, the restore process clears the AuthorizationCodeWithProofKey credentials from the SDx registration. To recover your data, you must re-register the restored model to the same SDx plant as was used for the previous SDx registration (that is, the SDx plant for the SDx registration of the empty Change Management model during the Phase One tasks). See Register the Change Management model with SDx.
After you re-register the restored model, define SDx retrieval settings if needed.
