Export Sales Order Preview to pdf UI/DI API

Hello everybody,

once a Sales Order is successfully added I want to export a .pdf file containing that sales order. I figured out there is an option to do it from File>Export>PDF (Menu UID 7176) but this way user is asked to insert specified name and path of file.

Second option is through Menu option Preview found under File>Preview (Menu UID 519) but once again I can not find a way to save displayed pdf for later use.

Is there a way exporting to pdf a specific sales order?

Kind Regards,

Dimitris
