When Save each row after editing is selected on the Editing tab in the Options window, single-row editing is turned on. During single-row editing, changes are saved to the Windchill RV&S server as soon as you leave the row. This means that virtually no limitations exist during single-row editing. Single-row editing is initially the default behavior. However, you can switch between this mode and multiple-row editing as long as no unsaved changes exist.
