SAP CPI Posting idoc (1:N) scenario

Hi

I am working on one iflow - where in I need to post idocs to ECC (1:N -> Scenario). Initially I had problem with highlighted segments below and I have removed them. Still I am facing problem and getting below problem.

Error Details com.sap.sod.utils.idoc.soap.protocol.IDocSoapProtocolException: [IDocSoapUtils][IDocSoapProtocol][GeneralProcessingError]:General error while processing IDoc XML, cause: com.ctc.wstx.exc.WstxParsingException: Illegal to have multiple roots (start tag in epilog?). at [row,col {unknown-source}]: [1,1302]

Can you advise if any have you faced this problem with idoc adapter ?

Thanks in advance
