About Defining Project Input and Output Variables

Project input and output variables are the input and output variables that are used by the champion model and challenger models. SAS Model Manager requires that the project input and output variables be defined before a champion model can be published to a production environment. You can define the project input and output variables when you create a project or during the champion model selection process.
You define the project input and output variables using one of the following methods:
  • Create input and output prototype tables and import the variables using these tables. You import the variables using the New Project wizard or the Modify Project Definition window.
  • Copy the input and output variables from an existing champion model. You copy the champion model variables using the New Project wizard or the Modify Project Definition window.
  • Use the Modify Project Definition window to add, modify, or delete individual input or output variables.
  • If you declare a champion model and the project variables have not been defined, SAS Model Manager prompts you to add model input variables to the project and to map model output variables to project output variables.
SAS Model Manager saves the input variables’ definitions in the file inputvar.xml and the output variables’ definitions in the file outputvar.xml. The inputvar.xml file and the outputvar.xml file are saved in the project folder. When you set a champion model, the inputvar.xml file and the outputvar.xml file are copied to the version folder.
