Which action would NOT be available to a user with insufficient permissions when checking in a batch?

The action that would not be available to a user with insufficient permissions when checking in a batch is the ability to reassign the batch. This is because the "Reassign To" action typically requires specific permissions that allow a user to change the ownership or responsibility for a batch of work, and users with insufficient permissions are restricted from performing such actions.

On the other hand, the options for "Check In As Completed" and "Check In As Pending" are generally operations that can be performed by users depending on the permissions assigned for batch checking processes. Therefore, these actions can still be available to users, even if their permissions are not sufficient for more complex actions like reassignment. Recognizing this distinction helps clarify how batch processing and user permissions interact within the system.
