Production Scheduling parameter variable substitution
          The parameter variables are used in commands to represent the specific context or elements that are replaced at run-time by a value specific to the current Production Scheduling context and settings. The parameter variables are validated at run-time. Therefore, all the variables are allowed when creating macros, or interface services. The context parameters such as %schedulingmodel% are assigned from the macro context. For example, a system macro containing the RunProductionSchedulingMacro command can apply the %schedulingmodel% context parameter when executed from Production Scheduling Model Details or a scheduling view.
         
         The parameters that are invalid for the function that is being run, result in the termination of the program, and an error message is displayed.
          Note: 
          
        - Variables are not case-sensitive.
 - If the variables are used for macro functionality, only one variable per parameter is allowed.
