Via the fields _Select Module Data Set File_ and _Select Module Data Set File Version_ , an alterative module data set can be selected. When an Operator Client is used an alternative module data set should first be loaded in the FEWS data base through the Configuration Management. When a Stand Alone system is used an alternative module data set can also be locate in the "\config\ModuleDataSetFiles" directory. The selected alternative module Data Set is actually added to the What-if Scenario by pressing \[Add to List...\]. This action can be repeated when required to add additional alternative Module Data sets to the list. |
