Working with Presentation Columns

The presentation column names are, by default, identical to the logical column names in the Business Model and Mapping layer. However, you can present a different name by clearing both the Use Logical Column Name and the Display Custom Name check boxes in the Presentation Column dialog box.

To provide a convenient organization for your end users, you can drag and drop a column from a single logical table in the Business Model and Mapping layer onto multiple presentation tables. This allows you to create categories that make sense to the users. For example, you can create several presentation tables that contain different classes of measures—one containing volume measures, one containing share measures, one containing measures from a year ago, and so on.

The Presentation Column dialog box has the following tabs:

• General. Use this tab to create or edit a presentation columns.
• Aliases. Use this tab to specify or delete an alias for a presentation column.
