Doing "What If" Experiments

You can experiment with using different instructions, one at a time, to test the "What If" results of these instructions. Any instruction, a deposit, a withdrawal, a transfer, a cost, a beneficiary, or a parameter change can be disabled temporarily, and then a calculation can be run to obtain the result without the effect of the disabled instruction. Then the instruction can be enabled and another instruction disabled for another calculation run to compare the results.

To disable any instruction, select its tree view node and click the Edit icon. Then click on the "Disable" check box in the data entry window to set it as checked. Click "Finish" and the instruction is disabled. The tree view display for the instruction's node is changed to red with a strike-through font. An example is shown below.

To enable the instruction, select its tree view node and click the Edit icon. Then uncheck the "Disable" check box and click Finish.

Experimenting With Parameter Change Instructions

If you want to try different parameter specifications to see the results of experimental parameters, you can define several different parameter change instructions, and then disable all but the one you want to test. This lets you disable the effect of a parameter change instruction without having to delete it. And you can enable it again without having to reenter the data. An example is shown in the figure below.

By using this technique, you can experiment with multiple sets of global plan details. Simply define several different parameter change instructions, all for the plan calculation start year. Each one is marked as disabled. Then you can modify the default global plan details as you wish. Just select one of the parameter change instruction and use the edit procedure to enable it. To change to another one, you must disable the active one first, otherwise an edit error is reported since there are conflicting parameters for the same year. See the figure below.
