APAR status

• Closed as program error.

Error description

• When a microflow calls another microflow it is normally assumed,
  that they run in the same UOW (transaction).  However, this is
  not the case, if the microflow is called via a dynamic endpoint
  or through late binding.
  This is because in such a situation, the process is invoked via
  a dynamic import which has joinTransaction and
  joinActivitySession qualifier to false.  As a consequence
  CWWBE0140W warnings can be observed in the log.
  

Local fix

• Put the called microflow into the same SCA module.
  

Problem summary

• When a mciroflow calls another microflow via dynamic endpoint or
  through late binding the transaction runs not in the same
  transaction (UOW) because the process is invoked via dynamic
  import which has joinTransaction and joinActivitySession
  qualifier set to false by default (which can't be changed).
  This results in the following warning in the log:
  
  CWWBE0140W: The process '...' is a microflow (not
  long-running) that is running in a transaction or activity
  session other than its invocation context.
  

Problem conclusion

• This fix enables customer to set a custom property to change
  this behavior.
  With the fix installed and the custom property being set, a
  chain of microflows that involves dynamic invocations is
  enforced to be run in the same transaction.  Dynamic
  invocations done from a long-running process are not affected by
  this fix.
  

Temporary fix

• Not applicable
