Error explanation
When downloading the ESEF package from the Workiva Report Tagger, the .zip file has a predefined name that is embedded in the package itself.
This error occurs when the ESEF package name does not follow the naming convention recommended by ESMA.
How to solve it
Check the name of your ESEF package. The naming convention, as described in Guidance 2.6.3 in ESMA’s manual, should be:
LEI CODE-end of reporting period-version-language.zip
Example: 1A2B3C4D5E12345-2024-12-31-0-en.zip
Important: Always make sure that your ESEF package follows the above naming convention.
Common Issues
The most common issues are:
- (1), (2), (x) being added at the end of the file name automatically upon downloading several packages in the same folder.
- Manual renaming of the ZIP file to include the Company name.
If you are required to change the name of your ESEF package, follow the steps in How to Change the Name of Your iXBRL File.
