Error with Asynchronous RFC call to JDBC

Question

Hi all,
We are working on a scenarion where in we have to make an asynchronous RFC call to JDBC.
We have configured RFC sender adapter following this weblog
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
We have created data types only for the database as RFC does not require any data types.
And also we have created message types,message interfaces accordingly.
In Message Mappping,we mapped the export parameters of RFC to the access fields of database message type.
Also we have created sender agreement,interface determinations etc.... accordingly
And for sending RFC request asynchronously we followed this weblog
/people/swaroopa.vishwanath/blog/2006/12/28/send-rfc-to-sap-xi-150-asynchronous
Once done with all the above steps we could able to trigger the RFC call and caught with the following errors in SXMB_MONI and no errors are seen in communication monitoring
SOAP Error:
+<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>+
+- <!--  Request Message Mapping+
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
Also trace shows the following error thogh the interface determinations are properly configured
<Trace level="1" type="B" name="CL_XMS_MAIN-WRITE_MESSAGE_TO_PERSIST" />
- <!--  ************************************

  <Trace level="1" type="T">--start sender interface action determination</Trace>

  <Trace level="1" type="B" name="CL_XMS_MAIN-PERSIST_READ_MESSAGE" />

- <!--  ************************************
  -->
  <Trace level="1" type="T">----</Trace>
  <Trace level="1" type="T">Starting async processing with pipeline CENTRAL</Trace>
the above errors are shown as part of request mapping..
Can any one please let me know what other configurations do we need to do?
I did not map the RFC import parameters,do we need to do that
Any help in this regard is really appreciated

Hi,
I am really happy to hear that the problem with mapping is resolved.
Now as per your requirment It needs to be aynschornous RFC--> XI ---> JDBC call. In XI you should map the RFC Export parameters to the traget structure of JDBC.
then the question is to how to trigger the RFC Function Module in R/3 to XI.
Plesae follow below steps to trigger it from SAP R/3
1. Create a RFC in the R/3 system
2. Configure the SM59 and Sender Communication channle as given in the Michal's blog. Also test if it is succesful.
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
3. Import the RFC in XI
4. Do the mapping to the target strucutre
5. Configure the JDBC receiver adapter
/people/sameer.shadab/blog/2005/10/24/connecting-to-ms-access-using-receiver-jdbc-adapter-without-dsn
6. You can trigger the RFC from R/3 sytem by using
Async Call - in ABAP program use below syntax to call RFC. Here the export parameters will be passed on to XI which further have mapped to JDBC.
CALL Function "RFC Name" IN BACKGROUND TASK destination <sm59 destination>
COMMIT WORK.
Sync Call
CALL Function "RFC Name" destination <sm59 destination>
Thanks
