Change of Number Series

Unfortunately, this cannot be done directly in the application. You can only manually overwrite internal document numbers (by enabling the "Allow manual overwriting of internal document numbers" option in the company settings under the "Other" tab).
​
The only faster option would be via the API, where you would use the ID to identify the specific document and then update the internal number using the <kod> element.
​
Example:
<winstrom version="1.0">
<faktura-vydana>
<id>10</id>
<kod>VF0125/2018</kod>
</faktura-vydana>
</winstrom>
