Flat-Idocs via the IDOC-adapter

Question

Hi All,
I want to send a flat-IDOC via the IDOC Adapter to a SAP R/3 system. The IDOC adapter does not accept flat-IDOC, but wants xml-IDOC. Does anyone know how to send this flat-IDOC to the SAP R/3 via ALE, but without XML-lizing the IDOC?
I am looking in to the principle of tunneling, but that will involve some ABAP coding.
Cheers,
Frank

Hi Bhavesh,
I tried, but the IDOC adapter wants XML. The receiver IDOC adapter checks the type of the payload and determines if IDOC tunneling is used or not. I don't know yet how to change the type of the payload:
<i>method CL_IDX_IDOC_SERVICE-GET_PAYLOAD, part of package SIDOC_ADAPTER
test if idoc is in tunnel-payload-format
    l_content_type = l_payload->getcontenttype( ).
    IF l_content_type = if_xms_resource=>mimetype_idoc.
      l_idoc_resource ?= l_payload->getdata( ).
      l_tunnel_flag    = 'X'.
    ELSE.</i>
and with tunneling the idoc must be stored in certain tables where the receiver idoc adapter will get the IDOC instead of the payload. And our flat-idoc is in the actual payload. So the direction I am looking into is an abap mapping, which will change the payload type and stores the flat idoc in these tables, so the idoc adapter is "fooled" to believe it is IDOC tunneling.
