When creating a custom report, which security domain do you not need access to?

When creating a custom report, access to any unconstrained security group is not required. Unconstrained security groups are typically designed to provide broad access without specific restrictions, meaning they allow users to access a wide array of data and functions within the system without the need for detailed security permissions.

On the other hand, access to the Custom Report Creation security domain, the security domain for the specific data source you wish to utilize, and the security domains for the fields being added to the report are all essential for ensuring that the report can be generated appropriately and that the user has the right permissions to access and include the necessary information. The need for specific access to these domains ensures that data security is maintained while allowing users to create reports that meet their needs.
