This method rolls back changes in one simple table or simple table view, whereas method RejectChanges rolls back changes in the whole data set. This method cannot be applied to composite tables. Also, it is not allowed to apply this method to a simple table that is used in a composite table as a main constituent table (is connected to its parent in the composite table diagram with a one-to-many relation; the restriction does not apply to those connected many-to-one). If one of these restrictions is not satisfied, the method throws an exception. In such case, use RejectChanges for the whole data set.
