UN/CEFACT's Modeling Methodology (UMM) is a UML profile for modeling global B2B choreographies. The basic building blocks of UMM are business transactions, which describe the exchange of a business document and an optional response. In addition to these businesses document exchanges, UMM business transactions mandate business signals that acknowledge the correctness of business documents. It is expected that a Business Service Interface (BSI) on each business partner's side reacts on incoming messages and on messages expected but not received. However the internal orchestration of the BSI is open to interpretations. In this paper, the authors demonstrate an unambiguous mapping from global choreographies described by UMM transactions to a BPEL-based orchestration of the business service interface.
