Attaching PDF form in QM02

Hi Experts,

I have a requirement where I have developed an Adobe interactive form for notification screen QM02 in the ACTION BOX.

After the PDF preview, the PDF document has to be saved in the attachments tab of the notification.

Can anybody help me in the same?

Since the PDF is just the output preview, does that get saved somewhere in SAP database?

Since the PDF is just the output preview, how shall I capture the PDF and save it in the attachment tab of QM02?
