You can submit timecards for approval when your administrator has configured approval processes in your organization. Approvers can then approve or reject timecards depending on the approval process. You can approve or reject a timecard using the standard Salesforce interface. See Approving and Rejecting Timecards.
You can approve and reject multiple timecards when your administrator has created an approval process and linked it to the Manage Timecards to Approve page. See Approving and Rejecting Multiple Timecards. The columns that appear on the Timecards section of the Manage Timecards to Approve page when approving or rejecting multiple timecards depend on the fields that your administrator has chosen in the field sets of the timecard object. For further information, see Timecard Field Sets.
