As you design your workflow, you create a modification by adding an EnableWorkflowModification activity to the workflow. The availability of the modification is determined by the EventHandlingScope activity to which you add the EnableWorkflowModification activity. Defining a modification adds a link on the workflow status page for that particular modification. When the containing EventHandlingScope activity comes into scope as the workflow runs, Microsoft Windows SharePoint Services makes the modification link available to the user. When the containing activity passes out of scope, Windows SharePoint Services removes the modification link from the workflow status page.

For more information on workflow modifications and modification forms, see Workflow Modification Forms (SharePoint Foundation).
