The PDF e-Invoice service, accepts only documents that are Invoices and Credit Notes. Any other document types like orders or catalogs are not accepted.

If your document is an Invoice or Credit Note and meets all the requirements, the issue can also be in processing (in most cases after a change was done to the layout) and the mapping needs to be checked by our Support Team.

For this scenario, please create a case and a Support Consultant will manually check yor documents.
