A Data Source may receive an Item Authorization Response, if applicable. Data Recipient provides a confirmation state of the item hierarchy (that has been synchronized to them) in the form of a 1SYNC Catalogue Item Confirmation (1SYNC CIC) sent back to 1SYNC. An entry will also be sent to the Data Source's Worklist. This state indicates if data synchronization should continue on the item data or not. The 1SYNC CIC Response (1SYNC CICR) is translated to the 1SYNC Item authorization Response and sent to the Data Source. An entry is also sent to the Data Source's worklist.
