How to get data from dynamic standard program RVADOR01 of sap?

Hi guys,

the standard programm RVADOR01 is running by output determination (ta: NACE)?

It creates a sap script form (ta: SE71). After saving an quotation(ta: VA22), I can save it as pdf.

Now I want to call the programm RVADOR01 in my own report to get this pdf or the data to create the pdf.

How can I do this? Copy it as z-program? How can I use the custom form defined in SE71?
