Specifying On-Demand Rules for Data Forms
You can create on-demand rules that can be run from data forms. On-demand rules are useful when you want to run only a subset of calculations to quickly see the results in the data form. For example, when you are working in a data form that has been set up to run a specific on-demand rule, you can enter data and then run the on-demand rule to quickly see the results of the calculation.
You create on-demand rules in the application rule file. The rules are created in a new subroutine and are identified by the OnDemand prefix, for example, OnDemand_Calculation. See Creating Rules Files.
