Hi Tilman, the xpacket is written now, but the PDF isn't recognized as PDF/A and has no metadata. Meanwhile, I've tried the CreatePDFA example which works. But there a new PDF is created, maybe this is the difference. The new modified PDF is available under https://files.fakturama.info/rhefiles/Testdok-modified-003.pdf.
