IDOC - SOAP scenario

Question

Hi Guys,
I have configured the IDOC-SOAP scenario and i am sending to the target business partner with the soap receiver adapter.
I did not get any wsdl from the business partner instead i got the xml structure, target url and soap action. I have created a xsd for the given xml and send the data to the business partner.
The data is reacing the target system but the xml document has error saying "invalid at the top level of the document" and no xml is seen. I also get an acknowldegment error in sxmb_moni as
OUTBINDING  CO_TXT_Routing_Back_Error
Error occured during back routing, error in communication channel
any help would be appreciated
Thanks,
Raj

I think this comes because XI requests Acknowledgement-IDocs by default. In many cases nobody processes these IDocs and so you get this error. Have a look at OSS-note 777175:
You are using Exchange Infrastructure 3.0 and receive IDocs using the IDoc
adapter. You want to be able to request acknowledgments separately in the
XI for each sending system and interface. In the IDXNOALE exception table,
you can deactivate acknowledgments for certain systems or interfaces.
Previously, you could only maintain the table with transaction SE16.
Report IDX_NOALE is delivered with Support Package 10. With the report, you
can add, delete and display table entries.
Report IDX_NOALE is extended with additional functionality as of Support
Package 11. This allows a sender system to request or deny acknowledgements
for all message types centrally. You can set exceptions to this central
setting by message type. Generic exceptions (for example, message type
'ORD*') are not supported. Entries that are already present in the table
are unchanged.
To perform these activities, you need the authorization to maintain IDoc
metadata (Object 'S_IDOCMETA' ID 'ACTVT' FIELD '02').
Hope this helps.
