Multiple responses to single request

I receive a single HTTP request, map this to an RFC and make a call to SAP. Straight forward so far but my problem is that the structure of the XML I send back to the 'requestor' will depend on the response from SAP.

For example, the following is sent if my call to SAP returns data











If SAP fails to locate any data


<ERROR>No customers located</ERROR>


Obviously everything starts with a message interface but it appears you can only have one 'input' message.

Thanks in advance.

    Ofcourse One Message Interface would have One Message (if the Interface is Synchronous, it would have req. and resp. messages). However you can create a Message type such that some node in the Message type can have multiple Occurances.

    And then While doing Message Mapping from RFC response to this Message you can create multiple occurances of the Node..

    Please elaborate on the Scenario further to help you find the resolution.

      Thank you. Your answer got me most of the way to solving the problem. As you state it's all about the message mapping. I've created a datatype with two nodes. One created if I get the data I need from SAP and the other created if I don't. Although I'm using a single message interface I'm returning different structures.

    Hi Robert,

    your requirement is just like HTTP(SYNC)-RFC(SYNC).

    both HTTP message interface and RFC shold be synchronous.

    you have to do two message mappings followed by one message mapping.
