Multiple files getting generated for file-file scenario

Hello Experts,

I am developing a File-File scenario using ICO. It is a $ delimited file. My file structure is as:

$Doc_Id$DocNo$Doc_SrlNo$Party_ID$

$001$100146$000001000$Super Sales

My data structure is:

MT_Invoice_HDR

   Header

       Details

                Doc_Id

                DocNo

                Doc_SrlNo

                PartyID

I am using the following FCC parameters to convert the file to xml.

Document Name: MT_Invoice_HDR

Recordset Name: Header

Recordset Structure: Details,*

Recordset per Message: 1

Details.fieldNames: Doc_Id,DocNo,Doc_SrlNo,Party_ID

Details.fieldSeparator: $

Details.endSeparator: $'nl'

Details.beginSeparator: $

But instead of creating one file in the receiver it is creating 9 files in the receiver end. Please help me to sort out this issue.

Thanks,

Sayanti
