If any updates fail then an error is returned and the Status property indicates the combined values of the operation and error status code.
The Status property for each Field can be used to determine why the Field was not added, modified, or deleted.
Problems with adding, modifying, or deleting a Field are reported through this property.
For example, if a user deletes a Field, it will be marked for deletion in the Fields collection. If the
Update call returns an error because the user tried to delete a Field for which
he does not have permission, the Status for this field will be adFieldPermissionDenied
or adFieldPendingDelete.
