To enable effective interorganisational collaborations, process providers have to disclose relevant parts of their local business processes in public process views. A public process view has to be consistent with the underlying private process. Local business processes are typically supported by transactions, which ensure a robust and reliable execution. Process views currently do not support the specification of transactional properties. This paper introduces transactional process views and studies how they can be constructed from an internal business process that is annotated with a transactional specification. This way, we provide a well-structured approach to obtain robust and reliable process behaviour at the public external level, thus facilitating trustworthy, fine-grained collaboration between organisations. We consider various transactional models. The feasibility of the approach is shown by means of a case study.
