hi experts,

i tried to use rest adapter polling with GET to retrieve file from URL with one dynamic parameter using "incremental token" where the current date should be set. the adapter should poll once a day, so I put 1 day in seconds as polling interval. so far so good, this works and polls once a day at the same time.

then we wanted to do a reliability test - we wanted to know what happens if PO is down at exactly this time, so we shut it down and after start up the adapter started polling and got an exception (comm channel monitor):

Error while processing inbound message. com.sap.engine.services.applocking.exception.AppLockingTechnicalLockException: The lifetime can not be the transaction, because currently no transaction is open.: The lifetime can not be the transaction, because currently no transaction is open.

what does it mean?

the message was polled but not processed, not visible in message monitor.

anyone got experience with this?

regards
