Disclosure Management – Extending a taxonomy
With the introduction of iXBRL for European Single Electronic Format (ESEF) filers will also need to create an extension taxonomy (note: this was already the case for US-SEC in XBRL scenario)
Within SAP Disclosure Management, we recommend the use of the Fujitsu XWand Taxonomy Editor
Note: this tool can be downloaded from the SAP Software Downloads
The following WIKI outlines the basic steps for creation of an extended taxonomy.
Thanks, Marc for detailed Explanation !!
Good evening Marc,
Thank you for the explanation and for the cmp taxonomy, they were both very useful!
We have a problem: when we try to save the taxonomy using the LEI code of the company, we get the error below:
LEI code generates invalid prefix error
We always get this error when using LEI codes, the only way to save it is by using a text string.
Do you know how to work this around? Could you please help us?
Thank you in advance,
Claudia
Hello Claudia,
Technically, I think the error is raised because of some invalid character you use (space ?)
See: https://www.fujitsu.com/downloads/INTXW/users-guide.pdf
- A prefix or a local name is not valid as NCName
If we look at the recommendation of ESMA
https://www.esma.europa.eu/sites/default/files/library/esma32-60-254_esef_reporting_manual.pdf.pdf
Guidance 3.1.5 Naming conventions for extension taxonomy files
The {base} component of the filename shall indicate the LEI of the issuer or the issuer’s name (or an abbreviation of it); it should be of no more than 20 characters in length.
The {date} component of the filename shall indicate the ending date of the reporting period of reference. The {date} component shall follow the YYYY-MM-DD format.
Most customers use the abbreviation of the name. You can see some examples here:
https://www.esma.europa.eu/field-test-esef
For example, AirFrance-KLM, the extension base is "afklm-20161231.xsd"
UCB uses "ucb-20161231.xsd"
Hope this helps
Marc
Thank you, Marc.
