An emc in-demand Administrator for your company can add or remove emc in-demand Data Managers, or change their privileges using the Contact Management System (CMS).
If you are an Administrator, CMS is located at: https://cms.medicines.org.uk/. The online CMS Help manual gives instructions on adding a new Data Manager and assigning or changing privileges.
If you are not an Administrator, please contact the person in your company who is responsible for emc in-demand and ask them to make the changes for you.
