Please add an autosave feature in SAS Visual Analytics while you are in Report Designer. If your session times-out while you are creating the report, you lose all of your work that hasn't been saved.
There is no auto-save feature in 7.x. However, auto-save was implemented beginning with 8.2. Reports are saved every five seconds. SAS Visual Analytics saves one draft of each report per user. It also saves a draft of a new report that has never been saved. Only the most recent version is saved.
