Setting ESEF Report Details

The Cell Documentation window displays the description of the currently selected cell or property as it’s annotated in the underling taxonomy, so you can understand exactly what to enter.

Validate ESEF Data

• At any time during report creation, and especially before exporting the report to iXBRL, you can validate data entered in the Excel template and filing pane. Validation ensures that the XBRL data being filed conforms to the XBRL specification.
• If a validation error is detected, the Validation Report window displays a message about the error and a hyperlink to the cell where the error occurred for easy troubleshooting.

Generate an ESEF Report

• Once your ESEF report is complete and valid, simply click the Export to iXBRL button in the ESEF tab of the Excel ribbon, and the add-in will generate a valid iXBRL instance document for submission.

Manage Taxonomy Versions

• The ESEF XBRL Add-in supports the ESEF XBRL Taxonomy from Version 2017 on. The list of supported XBRL taxonomies is periodically updated to include the latest versions, independently of Altova add-in releases.
• To view, install, update, and uninstall ESEF taxonomy versions, you can use the Altova XBRL Taxonomy Manager by selecting Manage Taxonomies in the Excel ribbon.
