This dialog appears when creating a new percentage (by clicking on the Create percentage button) or editing a percentage (by clicking on the percentage name).
To define the percentage:
The new Percentage is displayed on the Percentages tab.
To edit an existing percentage:
Once a percentage has been created, it appears in the report as a new measure. If your Measures dimension is in the slicer area, you must bring it into the rows or columns to see the new measure. Alternatively you can cycle through the Measures’ members until you reach the new measure.
To display both the original data value and the percentage, make sure the Display values and percentages together check box is selected in the Total and percentage settings dialog (see Selecting Totals and Percentages Settings).
