Failed Entries not visible in EOIO inbound queue

Hi Experts,

The scenario is HTTP->RFC (aysnchornous) i am specifying the queue name in the HTTP client itself (inbound EOIO queue) and i am posting the message from HTTP client to RFC in R/3 system. So after posting the requests i could not find the messages in the queues ( the messages appears in SXMB_MONI with a queue name say XBOQ0_LINE1), but i could not find the entries in this queue at all... COuld you help me what could be the reasons.. Do we need to set any queue parameters for the MEssages to stay?.

Quick response would be highly helpful.

Thanks and Regards,

Raj
