B2B-50081 Duplicated exchange protocol message error

Question

Hi,
I tested a scenario for ebXML inbound type. for the first time it worked correctly with no errors. i got instance created in my soa composite. but from the next time, even though i changed the input xml file name with unique message id, i'm getting the following error after acknowledgement or between the acknowledgement.
Please help me to solve the issue.
I'm naming the input xml as follows : <fromTradingPartner>_<DocumentType>_<Revision>_<msgType>_<msgId>.xml
Eg:OracleServices_ebXMLType_204_1_210820128.xml

Answer 1

I tried simple ebXML inbound use case only.
1.I created custom ebXML 2.0 document definition
2.created eBMS Channel for remote TP.
3.created Generic File Channel for host TP
3.created an agreement in the remote TP with these two channels and the document definition
4.Created a soa project in the jdeveloper with B2B adapter as sender(inbound), mediator to transform the xml to opaque(for .dat format) and then a JMS adapter as producer to put the the .dat file.
I tried this in 2 different ways:
If i configured the agreement without using the host channel (no channel for host and ebms channel for remote), instance for soa is been created with error since it is unable to convert to opaque format.
If i configured the agreement using the host channel (file channel for host and ebms channel for remote), no instance is been created in the soa but i can able to see the .dat file in the file channel's folder.In the reports page, msg and ack are generated correctly with one more error "duplicated protocol error".
Please help.
