HI,
When doing the exercise in TBIT40, I meet with a problem in HTTP to RFC. It always returns me such error msg in the html client: <SAP:Error><SAP:Category>XIAdapterFramework</SAP:Category><SAP:Code>MESSAGE.GENERAL</SAP:Code><SAP:AdditionalText>com.sap.aii.af.ra.ms.api.DeliveryException: java.lang.NullPointerException</SAP:AdditionalText></SAP:Error>
I don't know what's the exact reason for that, however, I am sure the BAPI program is not called. Using SXMB_MONI, we can see the response message (from Service: HEDCLNT001 Namespace: urn:sap-com:document:sap:rfc:functions Interface: ZBAPI_PO_CREATE) with above error and no XML payload at all. There's no error in the request message. I suspect if the communication channel is not created correctly as the document doesn't give a clear description on creation steps.
My question:
1. Is there any method to test if the RFC could be called properly from XI side using the communication channel I created?
2. What is the possible reason for the error I just met with? Any available solution?
Thanks & Best Rgds,
Jerry
