What is the different qRFC outbound and qRFC inbound Queue ?

[Former Member]

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.

Hi Fernand,

In simplest forms:

Sender side AE->Inbound queue(SMQ2)->IE->Outbound queue(SMQ1)->Receiver side AE.

Hi Pinangshuk,

As I know base on Harld Keimer comment

Thant SAP PI Inbound and Outbound Queue Technically implemented as qRFC Inbound Queue (SMQ2), so you will see XBTI* and XBTO* in SMQ2 not in SMQ1.

Sender side AE->Inbound queue(SMQ2)->IE->Outbound queue(SMQ2)->Receiver side AE.

What i would like to know what is the function for qRFC Outbound Queue (SMQ1) in PI Integration process ? So far i only can see when I have ccBPM Implemented it will be queue to SMQ1 first before SMQ2.

Any Idea ?

Best Regards

Fernand.

Dear Fernand

SMQ1 - qRFC Monitor for the outbound queue. You use this transaction to monitor the status of the LUWs in the outbound queue and restart any hanging queues manually.

SMQ2 - qRFC Monitor for the inbound queue. You use this transaction to monitor the status of your LUWs in the inbound queue.

Thanks and regards,
