Payload from B1 in table format instead of DI API

Hi people.

I just started with B1I but I've expertise in SDK development.

I implemented a B1_2_File scenario and it works fine but I don't understand because the payload from B1 is in table format instead of DI API one.

For example, although the inbound channel is typed "SAP Business One", the sales order appears so

<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>

  <ShipFromCo nil="true"/>

  <ShipFromDe nil="true"/>

  </row>

</RDR1>

<RDR12>

  <row>

  <DocEntry>387</DocEntry>

  <TaxId0 nil="true"/>

  <TaxId1 nil="true"/>

  <TaxId2 nil="true"/>

instead of something like DI SDK referencing <Documents>, <DocumentLines>, and so on.

Could you help me?

Thanks a lot

Nicola
