Problem Mapping FTP to IDoc

Question

Hi well i have following incoming structure:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_EPOSYS xmlns:ns0="http://XXX">
   <EPORecordSet>
      <EPOFileHeader>
         <BDKDNR>0000007531</BDKDNR>
         <BDART>T</BDART>
         <TEXT>Bestellung</TEXT>
      </EPOFileHeader>
      <EPOFileHeader>
         <BDKDNR>0000007531</BDKDNR>
         <BDART>T</BDART>
         <TEXT/>
      </EPOFileHeader>
      <EPOFileHeader>
         <BDKDNR>0000007531</BDKDNR>
         <BDART>T</BDART>
         <TEXT>4510</TEXT>
      </EPOFileHeader>
      <EPOFilePos>
         <BDKDNR>0000007531</BDKDNR>
         <BDART>S</BDART>
         <BDIDENT>000000000050504200</BDIDENT>
         <BDMENGE>0000002</BDMENGE>
      </EPOFilePos>
   </EPORecordSet>
</ns0:MT_EPOSYS>
this one should be mapped into IDoc Structure:
<ZBC11_EPOSYS_HEADER SEGMENT="">
         <KUNNR>0000007531</KUNNR> [ = BDKDNR]
         <BDART>T</BDART> [= BDART]
         <DATA>1</DATA> [ = TEXT]
         <ZBC11_EPOSYS_POSITION SEGMENT="">
            <BDKDNR>0000007531</BDKDNR>
            <BDART>S</BDART>
            <MATNR>000000000050504200</MATNR>
            <MENGE>0000002</MENGE>
         </ZBC11_EPOSYS_POSITION>
      </ZBC11_EPOSYS_HEADER>
   </IDOC>
</ZBC11_EPOSYS>
where it should be mapped to the fields in the brackets [].
Incoming occurence (File):
<EPOFileHeader> occurence should be 1...9
and <EPOFilePos> has occurence 0..9999999
Target Structure Occurence:
<ZBC11_EPOSYS_HEADER SEGMENT> 1..9
one level down:
<ZBC11_EPOSYS_POSITION SEGMENT=""> 1..9999999
so that there should be no problem to map several Header data and FilePos-Data to the IDoc structure.
Problem is that XI only takes one header and map all the FilePos-data right. But how to configure the mapping that the Header of the IDocs takes more than one incoming header and following FilePos-Data?!
Can somebody help me?!

Hi Jens,
>>Problem is that XI only takes one header and map all the FilePos-data right. >>But how to configure the mapping that the Header of the IDocs takes more than >>one incoming header and following FilePos-Data?!
i couldn't understand what do you mean by <b>XI only takes one header</b>.
Do you mean IDOC occurrence 1..1,if yes then
  export imported IDOC as external definition,
  Change IDOC occurrence as per your requirement and
  import modified IDOC as external definition in IR.
Thanks,
Jag
