Receiving Idoc as String (instead of typed) in WCF-SAP Adapter

Question

Hallo All,

I am trying to receive Idoc from SAP as Raw String.

In the WCF-SAP Adapter binding, I set the "ReceiveIdocFormat = String" (instead of Typed).

I get the Idoc as Xml with just 2 xml elements wrapping it. This is expected.

<ReceiveIdoc xmlns="http://Microsoft.LobServices.Sap/2007/03/Idoc/"><idocData> Idoc as String </idocData></ReceiveIdoc>

Now, in the Messages tab, I selected "Path-Content located by body path".

Body path expression = /*[local-name()=’ReceiveIdoc’]/*[local-name()=’idocData’]

Node encoding = String.

But it doesn't work. 

While sending a doc. from SAP, the process goes on and on. Nothing is received in BizTalk.

I also tried with this xpath //*[local-name()=’idocData’]/

Thanks for your help.

Answer 1

What do you mean by goes on and on?  You mean SAP doesn't get a response to a request/response?  This could happen if there was an error in receiving the message.  Have a look at your suspended instances and the Windows Application Log for errors.

Your XPath looks correct.  To test, set up a one-way Send Port with a filter of type BTS.ReceivePortName and set it to the value of your SAP port.  You can easily see the output of the Receive Port.

Hi Prabath 

Check the following-

1. What is the IDoc status seen from SAP? Does it show transmitted?

2. Does anything get logged in Windows eventlogs?

3. If the above does not help, try to setup a WCF-SAP trace-

Hi,

First try to save the idoc in whatever format you set-up in receive location to a folder and then check the content.

Are you able to save the idoc to the folder?

Thanks
