How to: Add Columns to a Mining Structure
Use Data Mining Designer in Business Intelligence Development Studio to add columns to a mining structure after you have defined it in the Data Mining Wizard. You can add any column that exists in the data source view that was used to define the mining structure.
Select the Mining Structure tab in Data Mining Designer.
Right-click the mining structure and select Add a Column.
The Select a Column dialog box opens.
Under Source table, select the table in the data source view where the column resides.
Under Source column, select the column that you want to add to the mining structure.
|If you add a column that already exists, a copy will be included in the structure, and the name appended with a "1".|
