Connectors in Update mode have an additional change-control feature called “Compute Changes”. This feature can be made to work with Delta Entries.
The “Compute Changes” feature can be enabled in an Update mode Connector by selecting a check box of that name in the Connector Detail pane. When turned on the Connector will compare its Entry with the actual Entry in the connected system. If the two Entries are equal no updating is performed by the Connector. So the “Compute Changes” option allows the Connector in Update mode to skips unnecessary updates. This is useful for data sources with relatively heavy update operations.
However when a Connector in Update mode with enabled Compute Changes parameter receives a Delta Entry, the “Compute Changes” logic will not be triggered; it will use the delta operation codes assigned to the Delta Entry to apply the necessary updates to the connected system.
