Every opportunity field history report created in my org is accessible from the profile I want to share it with, but no records appear. Only admins seem to be able to view records in them. The profile can reach those single opportunities without any problem and all of the fields related to the report as well. No problem with opportunity history reports. Can you help me? thank you
You cannot give FLS access on field history and they are controlled on field level only.
