XI IDoc adapter problem. MESSAGE.DUPLICATE_DE

[Former Member]

I have a problem with the IDoc. When sending the IDoc from the PI to ERP - system throws an error (ta SXMB_MONI):

 <SAP:Error xmlns:SAP="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="PLAINHTTP_ADAPTER">ATTRIBUTE_SERVER</SAP:Code> 
  <SAP:P1>500</SAP:P1> 
  <SAP:P2>Internal Server Error</SAP:P2> 
  <SAP:P3><SAP:Error><SAP:Category>XIProtocol</SAP:Category><SAP:Code>MESSAGE.DUPLICATE_DE</SAP:P3> 
  <SAP:P4 /> 
  <SAP:AdditionalText /> 
  <SAP:ApplicationFaultMessage namespace="" /> 
  <SAP:Stack>HTTP server code 500 reason Internal Server Error explanation <SAP:Error><SAP:Category>XIProtocol</SAP:Category><SAP:Code>MESSAGE.DUPLICATE_DE</SAP:Stack> 
  <SAP:Retry>M</SAP:Retry> 
  </SAP:Error> 

What could be the problem?

The problem is solved. The errors was in Receiver Determination.

The HTTP code 500 indicates internal error in your application.

Check on to the stacktrace in

<local drive>:\usr\sap\XXX\YYY\j2ee\cluster\server0\log

check note number 804124 at service.sap.com

You can also check:-

Ping the receiver host from XI server.

Have a look at the SMICM->Trace file

Test the connection of AI_RUNTIME_JCOSERVER

HTTP 500 can be any problem at receiver side. Are you sure, that the payload fits to the receiver requirements?

Also i looked up this message "MESSAGE.DUPLICATE_DE" this comes when duplication of message takes place.

Try chaning the input data.
