Local fix
Problem summary
The problem occurs when - BPC is configred to use work manager based navigation (WMBN) - the load is that high that WMBN's internal message pool cannot hold all navigation messages that are produced In this situation, BPC does not put messages into WMBNs message pool, but sends them directly to the bpeIntQueue via JMS. In addition it tries to mark the database record backing these messages with the info that the message has already been sent to JMS. Unfortunately, at this point in time the database record does not exist and this causes the error.
Problem conclusion
The fix checks for existence of the database record before attempting to update it. iFix available on top of V751 GA
