How to fix the error message: "error in incoming document"

This is what you do if you get the error message "error in incoming document":

1. Enter first the accounting module. When you are in voucher receipt, you see the error message at the top.
2. If you press click here to view, are you coming to administration, and module settings for the accounting module. Here you will get a log for voucher receipt. If there is an error with the voucher, you will see that the voucher is marked in red with the text "error".
3. If you press the button download in the column File on the far right, you can download the appendix. Some file types, such as docx files, will not be read correctly in Catacloud. Therefore, you can solve the problem by downloading the attachment and exporting the file as a PDF before uploading it again.
4. Tick the far right to mark that the error message has been handled. Then the error message will disappear in the voucher reception.
5. Go back to the voucher receipt in the accounting module and press upload at the top left, and select the file you want to upload.
   
   When the attachment is uploaded in the correct format, Catacloud can handle the file without any problems. You will then see that the voucher appears in the voucher reception without an error message.
