Error in Trace Level: could not create BPE proxy for message, no XML objec

Hi

We are doing a scenario of File to RFC using BPM and I am getting this errror in Tcode SXMB_MONI.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<!-- Call Adapter

-->

http://sap.com/xi/XI/Message/30" xmlns:SOAP=" http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

<SAP:Category>XIAdapter</SAP:Category>

<SAP:Code area="<b>BPE_ADAPTER</b>">UNKNOWN_MESSAGE</SAP:Code>

<SAP:P1 />

<SAP:P2 />

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack><b>No object type found for this message; check the activation of the corresponding process</b></SAP:Stack>

<SAP:Retry>M</SAP:Retry>

</SAP:Error>

And getting this error in Trace level

<b>could not create <b>BPE</b> proxy for message, no XML object definition found for message EB32BB50610A11DC9648001321CB837D</b>

Why this error occurs?

What could be in error?

Thanks in advance
