Which type of user access is characterized by limited functionality and cannot be modified?

The type of user access characterized by limited functionality that cannot be modified is the Adaptive Planning user. This user role is designed for individuals who need to interact with the planning system without the capability to change critical settings or data structures. Their access is typically focused on specific planning tasks such as viewing reports, entering data, or analyzing scenarios within set parameters.

Adaptive Planning users are often provided with a streamlined interface and predefined permissions that prevent them from altering essential configurations in the system. This limits the potential for errors or unintended changes that could disrupt planning processes, ensuring a more controlled and secure environment for managing data and collaborative planning activities.

In contrast, the other options represent various components or different permissions styles within the Workday ecosystem. GL Accounts, Child accounts, and Root accounts indicate types of accounts or structures that allow for different levels of access and management capabilities, which do not align with the characteristic of limited, unmodifiable user functionality associated specifically with the Adaptive Planning user role.
