I have 5-10 separate "Dashboards" that are compiled together from multiple Pivot Tables whose data is taken from multiple Datasource (20-30) Types (Excel, SQL Server, SSRS, .TXT, .CSV, etc.).
So for example I have Dashboard #1 is derived/compiled/displayed using data from 10 different Pivot Tables whose data is from 20 different Datasources.
Then I have Dashboard #2 which is derived/compiled/displayed using data from 7 Pivot Tables whose data is from 25 different Datasources.
Then Dashboard #3, derived/compiled/displayed using data from 9 Pivot Tables whose datra is from 22 different Datasources.
Then Dashboard #4, etc,..etc....
QUESTION: What is the best solution or "path-to-take" if my requirement requires me to take the SUMMARY DISPLAY DATA from each of my 5-10 Dashboards and then compile/consolildate them into a SINGLE DASHBOARD that will be used to COMPARE/ANALYZE the totals of each individual dashboard to one another and also provide performance variances, KPIs etc.
Does Excel 2010 using POWER PIVOT have any limitations especially in regard to DATASOURCES BEING USED? Is there a "maximum" number of Datasources issue to be aware of?
Please let me know if you need more info, I'll reply asap.
Any input/feedback is greatly appreciated?
