Combine IDoc and RFC Respone in one Message Type

Question

Hello,
I need to have the possibility to store the data of one IDoc and one RFC Response in one Message Type.
The structure should be something like this:
IDoc_AND_RFC_RESPONSE (root)
--item (0..onbounded)
ID (Attribute, type xsd:string)
IDOC (Elemtent, type IDOC <--unfortunately not possible in data type definition)
RFC_Response (Element, type RFC_Response <--unfortunately not possible in data type definition)
The goal is to merge 2 messages (idoc data and the data of a rfc response) into 1 message with logical connected items.
e.g.
IDOC (message 1)
--ID 01
IDOC_DATA_01
--ID 02
IDOC_DATA_02
RFC_Response (message 2)
--ID 01
RFC_DATA_0101
RFC_DATA_0102
--ID 02
RFC_DATA_0201
I need this data to be transformed into:
IDoc_AND_RFC_RESPONSE
--item
ID 01
IDOC
IDOC_DATA_01
RFC_RESPONSE
RFC_DATA_0101
RFC_DATA_0102
--item
ID 02
IDOC
IDOC_DATA_02
RFC_RESPONSE
RFC_DATA_0201
The problem ist NOT how to do the mapping, BUT how to define the data type of the target message.
The IDoc and the RFC have a very complex structure so manually building the structure is not possible.
Thanks for your help.

Hi,
thank you for your hints.
- How can I define one interface with 2 message types? I work with XI 3.0.
- Manually manipulatiing the xsd files is what I wanted to avoid (besides that, there is no possibility to get the rfc as xsd, only wsdl). Besides that, I tried to extract the IDoc xsd and imported it as message type, but there is an error message telling me "Schema to be handled does not contain a definition of type <Data Type Name>", whereas <Data Type Name> is the name I give to the Data Type. I tried the name of the IDoc Type here. Importing the xsd as external definition would work, but that would still not solve the problem as I cannot use the message in my data type definition.
Maybe I should specify the scenario a bit better:
I have an R3 System sending an IDoc.
The Idoc contains multiple items.
The data in the IDoc is NOT sufficient (and due to warranty reasons and company guidelines, it is not possible to add all the needed data to the IDoc).
Therefore, the IDoc is passed to an Business Process, where an RFC is invoked (input are the item IDs of the IDoc).
So afterwar the rfc call, I have all neccessary data per item in 2 messages, the IDoc and the RFC response.
Now I need to merge the data per item into one message.
This one message than is splitted into the several items and every item has to be sent separately. So I need a possibility to unite the IDoc with the rfc response.
Any hint?
Thanks a lot!
