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

• To 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

• IV45809 enables customer to set a custom property to change this
  behavior.
  With the provided 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

• Ifix available
