What is the difference between "Errors", "Warnings" and "Inconsistencies"?

When you prepare your ESEF file in our software, the system will notify you about all the issues that appeared while validating your report. Some issues will block the delivery of the file to the local authority and while others are acceptable, it would still be better to correct as many issues as possible. Please note that some of the notifications are strictly informative and do not require any actions from your side.

The three different types of issues are errors, warnings, and inconsistencies and. In order to navigate better through your report, it is important to differentiate between them.

Information about the issues will be displayed on the Inspector’s Validation page:

  • Errors

Errors are displayed in red and will most likely block your report from being accepted by local authorities, so you should always fix them. Errors are critical and require you to take action to fix them. You can read more about a specific type of blocking error in the following knowledge articles:

  • Warnings

A warning is an issue raised by the contents of your annual report. Please note that a warning is not a blocking error. It is simply a heads-up for you to recheck the data in your report.

In some cases, the warnings are strictly associated with the blocking errors, so as soon those are fixed, the warnings will disappear. You can read more about some of the warnings you might run into while inspecting your ESEF report in the following knowledge articles:

  • Inconsistency

Calculation inconsistencies are issues that will not block your report from being submitted. They are common and in most cases they are connected to roundings in your calculations. They could also arise if the calculations for the same account are made differently in separate statements. Please note that to avoid these you should align the accounts and the way calculations are made between the statements. Most commonly, you will run into this issue when the calculation is different in the Comprehensive Income and the Equity statements respectively.
