Is it possible to create a user for inventory only?
When creating users in R365, you have the availability to assign them different Primary and Secondary roles based on their role within your company and what they will need to do in R365. There is a secondary role that allows users to 'Approve Stock Counts'. When creating new users and assigning them different security roles, we typically recommend for you to login as the new user you created to see what their abilities and limitations are and if additional roles should be added or taken away.
