Parent elements
| Element | Description |
|---|---|
| Updates (Item) |
Contains an array that defines append, set, and delete changes to item properties. The following is the XPath expression to this element: /UpdateItem/ItemChanges/ItemChange[i]/Updates |
Remarks
Only certain properties support append operations. An attempt to append to a property that does not support appending will result in an error.
For update operations, only one property can be modified within a single request. That single property must be referenced in the Path element. The Item element in the derived classes can then only hold a single property that is in agreement with the single Path element.
Note
The Path element is abstract. It must be substituted by the FieldURI, IndexedFieldURI, or ExtendedFieldURI element.
