Contact your Licensor in order to arrange the change to the licence and delivery of new data.

At present, only new licences and new quotes can be submitted via the Product Requirements Catalogue (also called the shopping cart). In a future release, we hope to be able to allow amendments to existing licences.  

For an amendment, you can still calculate the annual costs within the Product Requirements Catalogue, but you will need to contact your Licensor directly in order to arrange the change to the licence and delivery of new data. 

For more information, on what to do if you wish to change your data requirements, see also our page on how to change your data requirements.
