Synchronize Method
You can use the Synchronize method to make the values in a business object instance match those of an integration object instance. This operation can result in updates, insertions, or deletions in the business components. The following rules apply to the results of this method:
If a child component is not present in the integration object instance, then the corresponding child business component rows are left untouched.
If the integration object instance’s child component has an empty container, then all child records in the corresponding business component are deleted.
For a particular child component, records that exist in both the integration object instance and business component are updated. Records that exist in the integration object hierarchy and not in the business component are inserted. Records in the business component and not in the integration object instance are deleted.
Only the fields specified in the integration component instance are updated.
