How manage outbound IDoc with QRFC in SAP CRM 5.O

Hi experts,

I want to manage outbound IDoc with QRFC. For doing it I selected the flag Query Processing in transaction WE20. When I run the program QRFC Monitor (RSTRFCM1) the system shows this error message:

Status is SYSFAIL.

"[SAP.111.9129] WMSAP Adapter: Missing notification

- Message type: IDOC INBOUND"

Can someone help me?

Thanks a lot in advance,

Lorenzo
