Working with plan variables

A variable is a convenient way to specify context for the execution of the demand sets and their demands. Values for variables that are defined within parent objects (such as plans and demand sets) can be used by lower-level objects, such as demands and constraints.

For example, you can define a plan variable called ExecutionTime. Then you can specify the value (in time) that you want a plan to be executed. You define a variable at a higher level (usually within a plan) and then reference it within a demand. When the value of a variable changes, all demands and plans that reference that variable automatically use the new value.

If you have the Change Administrator role, you can add, delete, or modify local variables that are referenced by function arguments and other variables.
