Hi Salva
Yes, but it's not obvious that PDF generation, as a native WooCommerce action, requires a "data export" module. I think I had that disabled since I wasn't aware of any data exporting functions in the free plugin, and there is no documentation about what the module does. Now I've looked in more detail, I can see a forum post by Pavel last year, before Export Pro was released, saying that the only export function of ATUM is PDF generation. If that's the case, maybe consider renaming it to "PDF Generation" module, as data export suggests something else entirely.
The PDFs are great, by the way. As is the Export Pro add-on!
