IDoc to Mail with attachment Scenario

Hi Experts,

at the moment I'm developping a IDoc to Mail message flow.

I have to transform the IDoc to a Papinet EDI-Message.

I want to use the Mail-Package because i want to change the subject, the receiver and the content.

I also want to keep the content as text.

The question is how to create and transfer the messages for the mail and the EDI-XML-Document to the mail receiver.

The result should be a mail with Subject and content and attached the XML-EDI-Document.

Is it possible to do that with SAP PI/PO?

If yes, how can i solve the problem?

A multi-Message - Mapping with a module?

I searched a lot in the SCN, but i found no tutorial for this kind of problem.

regards,
