Specify the format for a particular object if you are not getting the results you want. For example, you add a measure to a report and you want to see two decimals when you run the report. You set the number of decimals to two for the Number format type for the current layout. However, when you run the report, you see more than two decimals for the measure. To get the results you want, you must map the measure to the Number format type.
Click the object.
In the Properties pane, double-click the Data Format property.
Under Format type, click the format type to apply to the object.
To override any of the properties of the format type that were defined for the current layout, in the Properties box, click the property and specify its value.
