Hi SB,

trfcs enable async communication ie the quality of service is Exactly once(EO).While qrfcs enable async communication with the quality of service Exactly once in order (EOIO) which make use of queues.

Hi S B,

I wopuld like a little to wat my friends say.. The asynchronous mode of communication ie the QOS = EO/EOIO is a guarenteed means of delivery.. However in the Synchronous it is not so..

Also it is similar to the tRFC(transactional Remote Function Call) and qRFC(queued RFC). I am sure the link Suraj has provided will help u more..

Cheers,

Divya

Hi SB,

For <b>synchronous communication</b> the quality of service is <b>BE</b> (Best Effort). For <b>asynchronous communication</b> there are two modes of quality of service they are <b>EO</b> (Exactly Once) and <b>EOIO</b> (Exactly Once In Order). In EO the message is delivered only once, so that there is no duplication. In EOIO the message is delivered Exactly once and that too in the same order.
