This method can be applied only to simple table rows (or to rows of a table view based on such table). It cannot be applied to composite table rows. Also, applying this method to a simple table that is used in a composite table as a main constituent table is not allowed (if it 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). In such cases, use AcceptChanges for the whole data set. If one of these restrictions is not satisfied, the method throws an exception.
