Abstract: A method and system are disclosed for propagating data changes from a data change source to a data change destination via a replication mechanism. After receiving a change to a data entry by the data change source, the replication mechanism builds a data change object specifying a first change. After performing optional formatting and filtering operations, the replication mechanism renders the data change object available for transmission to at least the data change destination. The system provides the data change object to the data change destination. In an embodiment of the invention, the data change object is combined with a prior change on the same object to render a “net” change on the data object. The disclosed invention is incorporated by way of example into a database application/system for maintaining business objects such as sales orders, shipping, and other business transactions.
