RFC FM and tables parameter with complex type

I want SAP to deal with a middleware (WebMethods).

To do this, we notably use RFC FM.

For one I wish to use a table with complex structure (composed of fields of table type)

When I check the RFC enabled FM box, I have this message :

"Only tables with simple line structure are allowed in RFC"

There is a solution ? another way to proceed ?

It would be very helpful in the middleware side to receive this kind of complex structure (looking like IDOC)

Thanks in advace
