1043 Views

Dear SAP Expert,

I have search in SDN Forums and found a lot discussion and blog regarding qRFC. But I am still haven't got the clear picture what is exactly the different between qRFC Outbound (SMQ1) and qRFC Inbound (SMQ2) in XI.

As far as i know all transaction between R3 --> XI (RFC and IDOC) using tRFC.

qRFC only used for internal XI processing for Asynchronous message (inbound and outbound).

any idea when is SAP XI using qRFC Outbound (SMQ1) because i saw all inbound / outbound in PI technically implemented using qRFC Inbound.

what actually the different between qRFC Outbound and qRFC Inbound ?

Thank You and Best Regards

Fernand.
