Proxy to Webservice Synchronous Scenario

Question

Hi All,
I have a Synchronous Proxy to Webservice Scenario.
Here is the catch:
My Source Proxy Datatype is
DT_Source
    Status
     PayGradeA
     PayGradeB
Now the requirement is
if PayGradeA is equal to 01, 04, 05 then the data should be sent to WebserviceA and we need to get the response back to the Proxy,
if PayGradeB is not equal to 01, 04, 05 then the data should be sent to WebserviceB and we need to get the response back to the Proxy.
To handle this, in XI. I created
2  Receiver Communication Channels ,
2 Receiver Communication Components,
2 Receiver Agreements,
1 Interface Determination,
1 Receiver Determination, (In the Receiver Determination I gave the Conditions, if PayGradeA is equal to 01, 04, 05 and PayGradeB is not equal to 01, 04, 05 ).
Now when I trigger the proxy I am getting the following error
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <!--  Receiver Identification
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
  <SAP:Category>XIServer</SAP:Category>
  <SAP:Code area="RCVR_DETERMINATION">TOO_MANY_RECEIVERS_CASE_BE</SAP:Code>
  <SAP:P1 />
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText />
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack>Multiple receivers are not permitted in synchronous calls</SAP:Stack>
  <SAP:Retry>N</SAP:Retry>
  </SAP:Error>
I have read some blogs, they say XI wont support synchronous calls if we have more than 1 receiver.
I want to handle this without the use of BPM.
"Can we handle this in the ABAP Program in ECC?? If so can some body let me know how many Service Interfaces do I need to create in XI??"
Can somebody help me step by step.
Thanks,
Harsh

Answer 1

the other possibilitiy to avoid ccBPM is create a multimapping.
so in the memssage mapping define 2 target structures and you will create or not the root structures: for example:
If PayGrade is equal to 01,04,05 then create MT_PayGradeA
IF PayGrade is not equal to 01,04,05 create MT_PayGradeB
to do that in the message mapping add a new Message type in the target section under signature tab.
now if you will only receive values 01,04,05 so validate the routing rule defined in the Receiver determination.
