In the data synchronization log, several events can be logged for a unique record and event type combination. To prevent processing duplicate events, all logged events for a unique record and event type combination are further processed as one event. Finally, this results in only unique records in the outbound queue.
Example:
A sales order is changed several times. So, several events of type Update are logged for the sales order. When the data synchronization log is processed, these events are first grouped on one page. When the page is processed, these events are combined into one event for the sales order for further processing.
Note:
If you split logged events over pages, combining events for a unique record and event type combination is done separately for each page.
