Combine IDoc and RFC Respone in one Message Type

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.
