Question

Is there a way to perform a completeness check of the extracted data in the project.

There are three ways how to set it up:

1. Skip verification and data verification if the percentage of characters that need verification is equal to or less than 0% per document. To do this, open the project properties -> Workflow tab: 
   
   
2. Also, each important field can be marked with the "Requires verification" checkmark on the Document Definition level:
   
   
   
3. In case you wish to ensure that some fields (or all the fields) are non-empty at all, you may consider creating a script similar to the way it is implemented for the default EU Invoice Document Definition -> InvoiceDate field:
