It is possible to get a response of a asynchronous RFC call thru wait loop

379 Views

Hi Experts,

The requirement is that i queue up all the requests from a web services ( One queue per plant for example) which i set in the HTTP sender URL ( i mean the queue name ). and i am posting the records thru a RFC call.

1. Let the RFC call be synchronous and in case the R/3 system is done.. Will the XI queue keep the Call and keep on retrying it till the R/3 system is up.

2. Otherwise if the RFC call be asynchronous, is it possible to introduce a wait loop in BPM to listen to the RFC till i get some response ( i think this is not possible).

Need your suggestion on the same...

The requirement demands that no single request from the web service should be lost.. in case of failure of R/3 they should be queued up and re tried.. Forget about the error because of exception in RFC this will be taken care manually..

Thanks for your response in advance.
