You've executed a CSV upload in which you have modified some existing records, and created some new records. There were no errors during the upload. However, OTM is still retrieving only the old data, not the new data that was just uploaded.
You are writing an agent to be triggered when an Order Release Update is received via integration. You would like the agent to check if the Order Release is on a shipment and if it is, you want OTM to only update the Order Release.
