Customize Electronic Work Instructions preferences > Configuring the layout
EWI_AllowPreview
This preference displays the Show Electronic Work Instructions Preview command when you right-click a top- or step-level process in the Teamcenter Manufacturing Process Planner (MPP) application. When you define the EWI_step_url_domain preference, this command launches an Active Workspace viewer where you can logon and preview the selected process or step.
The browser view is controlled by the browserWindowMode preference. If you set that preference's value to 2 or 3, as you select different steps in MPP, the preview is updated.
Valid values are true (default) and false.
