例如，如果您正在显示一个有关作业信息的图表，就可以通过Change Context指定只在图表中显示带有特定名称或用户配置文件的作业。
For example, by using Change Context, if you were displaying a chart that graphed information about jobs, you could specify only jobs with a particular name or user profile are displayed in the chart.
然而，如果后来要求相同的显示属性，那么性能将大大提高，因为数据位于具有相同SAP BW安全配置文件的用户的DQM缓存中。
However, if the same display attribute is requested later, performance should be greatly improved as the data will reside in the DQM cache for users who have the same SAP BW security profiles.
如果用户的配置文件包含有效的元素，则Google Maps地图将显示在页面中。
If the user's profile contains a valid element, a Google Maps map appears on the page.
