Calculating financial information by using business rules
You can calculate the financial information by using business rules. This calculation can be used to represent the net costs and benefits over time in a project. The result is displayed in the business rule container attribute. If the values in the row change, the NPV is automatically updated. For example, you can calculate the Internal rate of return using the business rule TimeGridIRR.
