Scenario
User is trying to determine the difference between the system notes search results for an administrator and a non-administrator role even when both roles have the notes permission level set to full.
Solution
When viewing a system notes search as an administrator, users will be able to see all system notes changes set by any user. However, when logged in with a non-administrator role, the system notes search only returns results for the logged in user. Core Administration Permissions may need to be enabled on the custom role to see system notes of other users. For more information, see
