Is it possible, through the organizational units, to make sure that the different groups of operators see only partial personal data of the customers present in the data model in ACS?
Thanks in advance
It depends on what you mean with "partial personal data".
The organizational units only limit the access to a profile.
i.e. if you have access, you can see any field on the profile.
Unfortunately ACS has no feature to hide or limit access to certain fields (e.g. if you have a field TotalRevenue on a profile, anyone who has access to the profile can see it.
