Dear Mickael,

in addition to Prasanthi's answer let me briefly clarify how XI queues and qRFC queues are related.

The referenced document 'XI Asynchronous Message Processing: Understanding XI Queues -Part I'

explains XI queues in detail. From the logical point of view XI distinguishes between XI inbound queues

and XI outbound queues.

The crucial point here is: ALL XI queues are technically implemented as qRFC inbound queues. I.e. in

XI context transaction SMQ2 applies only.
