As announced earlier this year we have been preparing some changes to the GMDN Collective Terms structure following feedback from regulators and other big data users. This will help organize the GMDN Terms into more clearly defined groups and support better searching. This will involve no changes to the GMDN Terms themselves so your existing product assignments will not be affected. The main change will be the way the Collective Terms are presented in the Explorer and there are some CT name changes too. The change to the data structure was made on the 24th July 2021. If you have any concerns, please contact us.
