|Approvals are available in: Professional, Enterprise, Performance, Unlimited, and Developer Editions|
To view an approval request, open the Salesforce1 navigation menu and tap Approvals (or Approval Requests in the iOS downloadable app). A list of pending approvals for the current user displays. Tap a specific approval request to view the request details and then tap Approve or Reject. Approvers can also tap notifications to open an approval request, view request details, and approve or reject requests.
This item is included in the navigation menu by default. The layout can be configured using the Setup menu in the full site.
