SAP BO WEBI Reports Vs SAP Crystal Reports(CR) Vs SAP Dashboards(Xcelsius)?

The Datasource for Xcelsius is not limited to excel, it can fetch data through some data connectivity components like Web service, Live Office connection, SAP connection, many more…

1.   Webi & CR are reporting tools .Dashboard is Presentation tool. Generally Webi reports used for historical data and CR for live data.WebI is end user tool.CR is completely Developer tool. Dashboard is Developer Tool.
2.  Webi and CR are reporting tools and Xcelsius is a Dynamic Dashboard tool where we can provide a What-If scenario to the end-user.
3.  The output of the reports in Webi and CR are limited to pdf, word etc. But Xcelsius gives output as all the above mentioned formats and a unique format .swf (a flash file).
4.   In Webi and CR we can find the page refresh rate where as in Xcelsius we have buffered data. The advantage with this is unnecessary hits to the server may be reduced.
5.    Both Webi and CR cant competate Xcelsius in Look and Feel. Xcelsius has some rich features and some color blends.
6.     Webi and CR can hold huge data, but Xcelsius cannot hold bulk data. At runtime it shows the performance degrades and sometimes throws action script errors.
7.    There will be no ground work in Webi and CR in making data for charts but where as in Xcelsius we have to do lots and lots of ground work in the Excel sheet.
8.      Webi reports the source file has to be universe, where in crystal reportsource file can be anything, like universe, views, excel sheet etc, and for xcelsius the source file has to be only Excel sheet, and it also can take data live by using live office and query as a web service. 
9.      Through Xcelsius we can import data from Webi and CR through Live Office connector.
