XML Problem: RFC Function with XSTRING or raw table (4.6C)

hello,

I have a serialized XML-Document, i.e. a xstring or a raw table. Now I want to write a RFC Function Module that sends/receives this data. I'm running on 4.6C. Is this possible under 4.6C?

I've managed to write a Function module with appropriate parameters (XML in a raw table) that works fine, but I can't declare it as a <b>remote</b> function module. Is there a standard method of importing binary XML Data via RFC in 4.6C?

Regards,
