Send SD invoice to medium 5

Hello,

I created an output type for invoice (copy of RD00) and assigned it to medium 5.

Then I changed mail title to "Invoice: &VBRK-VBELN&"

Additionally I created an email body text (called "internal mail text" in SAP).

From technical side it works fine, but I have following problems:

- in the subject line I just get "Invoice:" without the doc. number

- the internal mail text from SAP doesn't appear in the eMail

- the pdf attachment is named ".pdf" ? I would like to have it in this way: <vbrk-vbeln>.pdf

Does anyone know how to fix this...?

Thx in advance!
