Use the Main Mappings panel to specify any variables to exclude from the output.
A dataset must be mapped to the Main Mappings panel once the action is defined for the first step. All subsequent steps will automatically be mapped to the same dataset. To map the data, drag the dataset from the Data folder to the Setup tab or use the 
icon in the Setup tab.
Use the option buttons in the Mappings panels to assign the columns in the dataset to the appropriate context associations.
None: Columns mapped to this context are included in the output.
Exclude: Columns mapped to this context are excluded in the result worksheet.
