The BPE implementation should support multiple business keys per process instance. This would enable process implementers to use different business keys for different bidirectional communication relationships. For example a communication between three parties A, B, C: If data is exchanged between A and C via B and Information needs to be returned from C to A via B, a different business key could be used between A and B vs. B and C. The current implementation only supports using the same business key between A and B as well as B and C since a return message event from C to B can currently only be correlated to the process instance at B if the business key matches the same one used to instantiate the process at B on behalf of A.
