The Setup tab allows mapping of control files to the object. The Mappings panel(s) of the Setup tab for the dataset displays the column headers specified in the script file. When Control File is selected in the Setup tab, the Text panel allows mapping of the file to the object and viewing of the script itself.
Map the data by dragging the dataset from the Data folder to the Setup tab or use the 
icon in the Setup tab. Once a dataset is mapped, use the option buttons in the Mappings panels to assign the columns in the dataset to the appropriate context associations. Required mappings are colored orange.
