Where to find EDI payload?? Seeburger monitor or RWB or SXI_MONITOR?

Hello Experts,

We're working on an ANSIX12 (AS2)--> XI --> Idoc (R/3) scenario. Everything is working fine. I just want to know where do I need to look to get the source ANSIX12 payload?

As far as I know, there can be 3 places to look for as follows...

Seeburger Message monitor - just has a log of the transaction..not the payload.

XI RWB - Contains the XML version of EDI (BIC mapper had already converted EDI flat file to XML format).

SXMB_MONI - Contains the XML version of EDI (BIC mapper had already converted EDI flat file to XML format).

Where else should I be looking? I'm sure there must be a place to look for the actual raw incoming EDI payload.

Your help is much appreciated. Please advise.

Thanks

Karthik
