Check the Status of a SharePoint 2010 Approval Workflow
Because the notification and task include a link to the Pending item, an approval workflow is a good way to get the input of users who otherwise won’t go to SharePoint 2010. And approval workflow facilitates an exchange between the Approver and the author of the content by allowing the Approver to provide feedback on the document (better to have dubbed it Review workflow).
Requestors and Reviewers can check the status of an Approval workflow as follows:
Navigate to the site for which you want to check the status of one or more Approval workflows.
Choose Site Actions→View Site Content Reports.
The Site Content and Structure page appears.
To view the status of items specific to you, select an item from the View drop-down list:
For Requestors, choosing Pending Approval displays all items that you've submitted for approval and aren't completed yet.
For Approvers, choosing My Tasks displays all tasks, including Approval workflow tasks, assigned to you.
To view all tasks (your own as well as those assigned to other people), click Workflow Tasks in the navigation pane on the left and then choose All Tasks from the View drop-down list.
The Workflow Tasks – All Tasks page appears.
Click any task to view its details.
A light touch with Content Approval and Approval workflow can help facilitate reviews, support governance policies, and help you track and retain information about whether content has passed the right checkpoints before being formalized. Experiment with them alone or in combination until you hit on the process that works.
