The interaction behavior between processes of organizations and their suppliers can be modeled by using choreographies. When an organization decides to gain more control about their suppliers and to minimize transaction costs they may decide to insource these companies. This also requires the integration of the partner processes into the organization. In previous work we proposed an approach to merge (consolidate) interacting BPEL process models of different partners into a single process model by deriving control flow links between the process models from their interaction specification. In this work we are detailing this consolidation approach. Thereby, special attention is turned on extending the consolidation operations in a way that process models with fault handlers can be merged.
