In the Pending Approvals page, the Skip Current Assignment option in the Actions menu or Task Actions menu is displayed only to users with the System Administrators role. This option is not displayed for end users.
Skipping the current assignment is not a valid action for an approver. If an approver chooses this action, then the corresponding request fails. Therefore, this option can be hidden for system administrators also. See "Hiding the Skip Current Assignment Option" in Developing and Customizing Applications for Oracle Identity Manager for information about hiding the Skip Current Assignment option.
