I recently created a new view, to extract data from our purchase order module. After a month or so of use, I realize that I'd like to make some enhancements. However I no longer able to edit filters, add calculated columns, etc. by using the pull down menu. Can someone explain how to edit the view after it has been created? If I view the filter toolbox, and then right click the filters listed, I can bring up the edit filter dialog box. However I still can't edit calculated columns, and the edit filter option is still unavailable from the pull down menu. Is there another procedure to be able to edit a view after it has been created and run?

Thanks
