Asynchro and Synchro in Service operation in XI

[Former Member]

Hi all,

could anyone explain why it is important to define asynchronous/synchronous for service operation in XI? What are the rules for these?

Is asynchro/synchro only related to a service operation call? or the service operation itself?

Why is asynchronous a prefered XI-based service?

Does that have sth to do with consumer, or both consumer and provider?

Thank you and best regards

Hi,

You would define a service as Asynchronous when you do not expect the target system to send a reply back to the requesting application, whereas in a Synchronous service the source system expects a reply from the target system provided that the target system is capable of providing one.

This is a general concept and not only relate to service calls in XI.

It is a relative call between the source and target systems.

Hi Amar,

so it means, a service definition is different than the service call, both could be asynchro or synchro. If I could use different call patterns why should I define the service pattern with asynchro/synchro?

Thanks
