At the end of the documentation page it says:
Introduced in 2012 (9.0)
Note that all built-in function should show up as Black in the notebook. You can clearly see that RandomFunction and WienerProcess are blue in your screenshot, meaning that they are 'unknown' to the system.
Try this:
tData = RandomFunction[WienerProcess[], {0, 10, 0.1}]; ListLinePlot[tData, Filling -> Axis, AxesOrigin -> {0, 0}]
