A formula is a mathematical expression that performs a calculation. To make creating a business rule easier, Business Rules provides four different formulas that you can insert into your business rules:
These formulas are the most common types of calculations you need your business rules to perform. All formulas provide you with a custom toolbar to customize the formula to suit your needs.
The common steps in defining formulas are:
Each formula has the following three tabs:
Formula tab—Use the Formula tab to enter destination and source details for each part of a formula. Each formula contains a destination and at least one source. You can add additional sources, calculation functions, number operands, operators, and parentheses using the custom toolbar.
Formula Range tab—Use the Formula Range tab to define the range of members, functions, and/or runtime prompts common to this formula. The range tab more narrowly defines the business rule range.
Data Condition tab—Use the Data Condition tab to specify certain data criteria that must be met before a calculation is performed.
