In which circumstance can "Reassign" not be utilized during metadata certifications?

"Reassign" cannot be utilized when there is only one certifier available because the purpose of this function is to delegate certification responsibilities to another certifier when needed. If there is only one certifier, there is no one else to whom the responsibility can be reassigned, effectively making the reassignment process impossible.

In scenarios where conflicting information is present, reassignment might still be necessary as it allows for resolution of discrepancies. Similarly, in role ownership verification, reassignment can help distribute certifying duties among multiple stakeholders. During access approval processes, reassignment can also be applied to ensure that the right individuals are assessing access requests. However, in the context where only a single certifier exists, the option to reassign simply does not apply, as it requires alternatives to carry out the certification effectively.
