How can I read PI payload - any sap table / function module ?

Hello PI Gurus,

I need to find out the number of records in a PI Payload. Is there any SAP PI table / function module available to get the number of records for an PI interface without going inside the actual payload in SXI_monitor.

I know table SXMSCLUP / SXMSCLUR captured the cluster information for PI payload in compressed form. But I don’t know from where I can get the actual message and hence number of records counts.

Best Regards,
