Microstrategy Report Services documents and dashboards

Microstrategy Report Services documents vs Dashboards A MicroStrategy Report Services document displays data coming from multiple reports, with the data laid out and designed in presentation-quality format. Most data on a document is from one or more underlying datasets. A dataset is a standard MicroStrategy report. Other document components that do not originate from the dataset, such as static text used for a title or heading, page numbers, and images, are added by the document's designer and are stored in the document's definition. A Report Services (RS) dashboard is a special type of document. An RS dashboard is commonly only one page long, is intended to be viewed online, and usually provides interactive features that let analysts change how they view the dashboard’s data, as well as what data they are viewing. A broad selection of widgets and a wide variety of formatting options allow you to design a customized, interactive dashboard. Both documents and RS dashb...
