Hi
My Customer wants a PDF/A-3a Document.
If he checks the pdf he get an error:
"
the key type is required but missing.
the document doesent provide appropriate structure information.
the document is not conform the PDF/a-3a standard.
"
I user the AsposePdfFormat.PDF_A_3A Format.
How can I set the “key type”?
Would you kindly share the sample code snippet being tried to convert PDF to PDF/A-3a. Also, please share a sample source PDF document with us. We will test the scenario in our environment and address it accordingly.
Hi.
The code uses your .dll. The source code is in Microsoft NAV an ERP System.

As per our understandings, you need to create a PDF_A_3A document with an attachment of XML file. You are able to do it and Adobe Reader shows it as well. But there is some other software which is unable to load the attachment from generated PDF/A document.
Please let us know if our understandings are incorrect. Also, please let us know about the other software which you are using to view the PDF files. We will further proceed to assist you accordingly.
Yes ist is correct: PDF_A_3A document with an attachment of XML file
I use the PDF Viewer: Foxit. The Viewer has no problem to show the included XML.
But:
I generate the PDF to use it für X Invoice (Zugpferd): I send an invoice to a Customer in optical form (PDF) and xml Form.
There exists software to check the PDF_A_3A document with an attachment of XML file
Example:
This Validaten tools throw an error:
"
Es konnte kein ZUGFeRD XML aus dem PDF extrahiert werden.
warning - No valid ZUGFeRD file.
