How do I create complex value driver formulas?
One of the great advantages of using LeveragePoint for your value modeling (vs. spreadsheets, for example) is the user-friendly handling of complex formulas. The key is to make smart use of the sub-formula capability.
Sub-formulas can be created in two basic ways:
1) Convert an existing variable to a sub-formula;
2) Merge two or more existing value drivers
Sub-formulas can then be reused across multiple value drivers. To do so add the sub-formula as you would add any existing variable with the type-ahead search.
To then modify a sub-formula in one place only, use the Make Unique option, found in the Variable options menu (otherwise, the sub-formula will be updated in every place where it is used). Then, use the Make Unique option for each variable within the sub-formula which should differ from the original.
