Hi ,

tRFC and qRFc are defined in Quality of services...

The difference between qRFC and tRFC is the demanded Quality-of-Service (Q-o-S). With qRFC, it is the Q-o-S exactly-once-in-order (EOIO) and with tRFC it is the Q-o-S exactly-once (EO). To be able to guarantee the sequence of qRFC units and, at the same time, parallelize independent units, the dependencies are implemented using queues in qRfc . tRFC units do not belong to a queue and can therefore always be processed in parallel.

Thus in Qrfc a particular order is followed while processing, while in Trfc it is not.

Check these..

Hi Ricardo,

just I would like to give one more comment.

qRFC is a great thing as the others described to control your RFCs and to use parallizing and so on...

One thing you should keep in mind:

If in a queue an entry stops because of (for example) an application issue, all the following entries will wait in the same queue...

This can impact your business as well and might happen if something not correctly set.

Hi,

first of all qRFC is just an extension to tRFC

the main difference is that when using qRFC

you can put all your calls/messages in a queue

so they get executed one by one which is not the case

with tRFC as with tRFC they get exectued without

retaining the original sequence

(so last call can be executed first)

with XI (sender RFC adapter) you can only use tRFC

but with a little RFC wrapper it is possible

to invoke qRFC calls from XI on the R3
