Add Source Levels to a Dimension

Source levels obtain values for their categories from columns in the Data Sources list. You can add source levels to a dimension either on the Dimension Map or in the Categories diagram.

Suppose the Region dimension of your sales model has three levels: Region, Country or Region, and Branch Name. You add sales representatives to the Region dimension by selecting the Sales Rep column from the Data Sources list and dragging it to the spot indicated in the following image.

Tip: You can create a default time dimension with Year, Quarter and Month levels by setting the Data class on the General tab of the Column property sheet to Date and dragging the column to the Dimension Map.

Procedure

  1. In the Data Sources list, select the column for which you want to create a source level.
  2. Drag the selected column to the appropriate location on either the Dimension Map or an existing level in the Categories diagram.

    On the Dimension Map, Cognos® Transformer shows a small outlined box where it will create the new level.

    On the Categories diagram, Cognos Transformer inserts the new level to the left of the level on which you drop the source column.

  3. Open the Level property sheet to set or modify the level properties and click OK.
    Note: Source levels can also be added by selecting an existing level on the Dimension Map or Categories diagram, clicking Insert Level from the Edit menu, and specifying the Associations for the new level.
