No. QuickLink Populations do not determine which identities can approve access requests. In SailPoint IdentityIQ, QuickLink Populations control the availability and scope of QuickLinks for users. They define who can initiate a specific request action, what type of request can be launched, and in many cases who the request can be submitted for. For example, they may allow an employee to request access for themselves or allow a manager to request access for direct reports.
Approval authority is handled separately through request workflows, approval schemes, approval rules, work item assignment logic, application or role owners, managers, governance groups, or configured business processes. When an access request is submitted, IdentityIQ evaluates the configured approval path to determine which identities receive approval work items. That approval routing is not controlled by the QuickLink Population itself.
Therefore, the statement is inaccurate. QuickLink Populations govern request initiation and visibility, while approval routing is governed by workflow and approval configuration.
