Any ActiveData that is updated in an expression during visual test playback is automatically saved back to the ActiveData file when playback successfully completes. If data from various cells in an ActiveData file has been changed, Silk Test Workbench saves the updated data back to the same cells unless other cells are specified.
Rather than waiting for successful playback to save data automatically back to the ActiveData file, you can create a step to immediately save specific updated data. The step only saves selected ActiveData that has been updated to that point in the visual test. ActiveData that is updated after the step executes is saved upon successful playback, unless the automatic save is cancelled.
