Payload from/to B1 in DI API format

Hi people.

This is a simple question from a B1I newbie.

How can I acquire in inbound to B1I from B1 the payload in DI API format?

I defined the B1 channel as "SAP Business One" but, acquiring, for ex., a sale order, I receive a payload like this 

<ORDR>

  <row>

  <DocEntry>387</DocEntry>

  <DocNum>387</DocNum>

  <DocType>I</DocType>

  <CANCELED>N</CANCELED>

  <U_IOE_POG_NRDOC nil="true"/>

  </row>

</ORDR>

<RDR1>

  <row>

  <DocEntry>387</DocEntry>

  <LineNum>0</LineNum>

  <TargetType>-1</TargetType>

...

instead of something like this

<Documents>, <DocumentLines>, and so on.

Could you help me? 

Thanks a lot

Nicola
