How Identity Cloud assesses synchronization situations
Identity Cloud performs reconciliation in two phases:
Source reconciliation accounts for source objects and associated links based on the configured mapping.
Target reconciliation iterates over the target objects that were not processed in the first phase.
For example, if a source object was deleted, the source reconciliation phase will not identify the target object that was previously linked to that source object. Instead, this orphaned target object is detected during the second phase.
