Problem with WCF client calling one-way operation

Question

I have run into a problem when calling web service on a SAP PI bus from my WCF client. The operation is defined as one-way, and the method on my proxy operation contract is deco

Answer 1

It looks like SAP PI incorrectly sends an empty SOAP envelope and .NET incorrectly interprets that envelope.

Some options from this thread:

• alter the generated proxy and remove OneWay=true (or add OneWay=false) to the method definition
• catch the Protocol Violation in an exception handler and ignore it
• use a 2.0 style webreference to call the service
• apply SAP patch Note 1459995 - Soap Sender Adapter HTTP 202 and add &responsecode202=true to the url

The first and last options both worked for me. Further discussion on this sap.com thread.
