Unfortunately, we couldn't find the answer to the question below in the documentation/community, so we're asking it here.
When migrating an existing application to the SF environment, all roles, etc. are also migrated.
It turns out that sometimes different roles set permissions on the same objects (tables/fields).
Unfortunately, it appears that some (also migrated) user groups contain multiple of these roles, leading to "rights conflicts".
Example:
role seller has read-only rights to a field in table A
role controller has write permissions on that field in table A
User group "Special employees" contains both roles
Is our conclusion correct that this means that for users with the user group "Special employees" they can only read the field in table A?
Are the lowest rights assumed by default?
Is this a setting that can be set at the application level?
Can we provide insight into these types of "conflicting rights" somewhere?
FYI: We use the Windows GUI
