3.24. Turning Inputs On and Off

Applies to: @RISK 5.x–7.x

Is there an easy way to turn input variables on and off? I would like to try a simulation with some of the variables turned off, but I don't want to replace the distribution formulas with constants because I will want the distributions to vary again in later simulations.

Yes, you can lock any inputs. To lock an input, do any of these:

In the Model Window, right-click the input and select Lock Input from Sampling. (You can select multiple distributions with Shift-click or Ctrl-click, and lock all of them in one operation.)
In the worksheet, right-click the distribution and select Define Distributions. In the Define Distribution dialog, click the fx icon near the top right to open the Properties dialog. On the Sampling tab of that dialog, click Lock Input From Sampling.
Edit the distribution formula in the worksheet to insert a RiskLock( ) property function.

During a simulation, a locked input always returns its static value (if specified) or alternatively, its expected value, or the value specified through the options under When a Simulation is Not Running, Distributions Return of the Simulation Settings dialog.
