Not able to see RFC inbound messages in SXMB_MONI of SAP R/3

Hi Experts,

I am working on MDM->PI->RFC scenario. When a record is syndicated from MDM, I am able to see that in PI monitoring but I am unable to see the message in SXMB_MONI of SAP R/3 system. SAP R/3 system is 4.7 systems with SAP_BASIS 620.

I have maintained LOGGING 1, TRACE_LEVEL 3 in SXMB_ADM->Specific Configuration->RUNTIME settings. I have activated the service /default_host/sap/bc/xmb. Still I am unable to see the messages in SXMB_MONI. Is this problem with the SAP R/3 version I am using? Am I missing any other settings?

Regards,
