Error -43 (The report output is not PDF/A compatible)¶

The error message you've provided suggests that there is an issue with creating a PDF file in compliance with the PDF/A or PDF/ZUGFeRD standards. PDF/A and PDF/ZUGFeRD are specific standards for PDF documents that ensure long-term archiving and support electronic invoices, respectively.

Here are some possible reasons for the error:

1. Insufficient Metadata:
   PDF/A and PDF/ZUGFeRD standards often require specific metadata to be included in the document. Metadata includes information like document title, author, creation date, etc. Check if all necessary metadata is provided.

2. Font Embedding:
   The standards may require that all fonts used in the document are embedded to ensure consistent rendering across different systems. Make sure that fonts are embedded in the PDF.

3. Color Management:
   Compliance with PDF/A may require proper color management. Ensure that color profiles are embedded if necessary.

4. File Structure:
   PDF/A and PDF/ZUGFeRD have specific requirements regarding the file structure. Ensure that the file structure adheres to the standards.

5. Interactive Features:
   Some interactive features may not be allowed in PDF/A or PDF/ZUGFeRD. Ensure that interactive elements comply with the chosen standard.

6. Document Structure:
   The structure of the document might not be compliant. This includes the arrangement of content, layers, and other structural elements within the PDF.

To resolve the issue, you should review the requirements of the chosen compliance standard (PDF/A or PDF/ZUGFeRD) and ensure that your PDF creation process meets all the necessary criteria. If you have access to any documentation or guidelines for the software or tool you're using to generate the PDF, consult those resources for specific instructions on achieving compliance with the desired standard.
