I can't upload a document

The main reasons why it may not be possible to upload a document to Exactian are:
  1.  That the file name contains special characters (example: ´*¨ []).
  2. That the file size exceeds 20 MB.
  3. That the internet connection is poor.
  4. It can also originate from the fact that the document has already been submitted for that period (monthly documents and single submission).
Verify that the document meets these requirements.
