This is a tool for creating homonymous graphical reports, built on of Microsoft Silverlight technology, and based on data from the Model. It allows creating rich graphical reports that show tabular data, charts, time-oriented charts, maps… Interconnection of its elements makes it an effective tool for making dashboards, and can be used for creating similar SharePoint reports.
Similar as you encountered working with Pivot tables, PowerPivot reports also enable creation of interactive charts. Unlike those made by traditional Pivot charts they can be independent, which means you do not have to be directly connected to the pivot table; you can use data already contained in the Model. Together with slicers and timeline filters they can be used as a tool for creating rich dashboards
In addition to options we use on daily basis Data model has some advanced options too. With them, we can define the perspective view on the table. Also, we can determine the behavior of columns when they are dragged in the Pivot Table, as well as to set additional attributes table that can be used when creating reports. Finally, it is possible to make one or more synonyms for each column, which later makes it easier to search the model.
DAX functions with the prefix “ALL” are used to engage or disengage filters in Power Pivot reports. These may be implicit filters, we have created by dragging dimensions in Filters field, but more often it comes to interactive filters- slicers and timeline, we use to filter Pivot Tables. The recipe that follows is about a report with a comparative review of these functions for their better understanding.
CALCULATE is one of the most commonly used functions in DAX. It is used to calculate expressions, usually given by some aggregation function, with use of one or more filters. It is not incorrect to use CALCULATE without a filter, but that’s not much point. The strength of this function is the ability of combining expression with a range of DAX functions that narrow set of data to perform aggregation with…
