The following points describe the diagram:
- Records are created in pending status. A user may transition the record to the canceled state.
- The MPL processes records in pending and retry status. While the record is being processed, it is changed to in progress.
- Based on the results of the processing, records could be transitioned
to error or complete.Note: An NDS is set to error if there is a problem with the NDS or if any of its related XDS records are in error.
- A user may cancel a record in the error state or change the status to retry to have the MPL try again.
