15-09-2025 Improved ‘add-on’ validation files for additional checks starting from 2025Q3

In the news release dated 10-07-2025, it was announced that starting from reporting period 2025Q3, a number of (automatic) checks—also known as validation rules—will be added to MESREP.

The corresponding files containing these validation rules still had some imperfections, which have now been corrected (please see the Excel file Add on validations MES_3.0.0_Excel_v2 and the XML file (for reporters who report in XBRL) Add-on validations MES_3.0.0_XML_v2). 
In the Excel file concerning these ‘add-on’ validations, the changes have been highlighted in the last, yellow tab.
