Home > Data Nodes > Data Source Node > Define Data Source > Select Attributes
By default, the Define data Source wizard includes all columns in the table or view.
If you do not want to include a column in the data source, move the attribute from Selected Attributes to Available Attributes. Click OK or Finish to end the definition.
When you edit a Data Source node, this selection allows you to deselect attributes. See Edit Data Source Node for information about editing.
