Delta processing

The Command Manager processes delta structures in a manner analogous to that of after-image data. The difference is that, for delta objects, comparative data is extracted from service data object change summaries.

When the input service data object (SDO) represents an Update operation with a delta structure, the Command Manager will look up the BOChangeSummary to find the respective operations on each child SDO.

For example, the following figure shows a delta SDO input with underlined text representing the operation derived from the change summary.
