Reusable canonical e-business process

A system and method to facilitate a reusable canonical e-business process is provided. A two-layer approach is employed. With regard to incoming information, a first level includes one or more external interfaces which transform information received (e.g., from an external trading partner) into an internal standard format. The internal standard format is then used by a second level internal interface to facilitate an internal business process. Similarly, for outgoing information, information is first processed by an internal standard interface and then transformed from an internal standard format into external standard format(s) by appropriate external standard interface(s).
