Below are the steps to remove the transaction timeline for a specific role:
--Navigate to Customization > Scripting > Script Deployments.
--Look for customdeploy_tt_bar_ue and click Edit (the related script is TT Widget UE).
--Under Audience tab, notice that All Roles box was checked. Uncheck this box and choose the role/s that you want the transaction timeline to appear (example: Administrator, Accountant).
Transaction timeline will only show to the role/s selected.
