Hi Community,
I would like to highlight Some common mistakes we tend to make for report tool selection (Web Intelligence & Crystal reports)
Problem 1: Hundreds of pages in SAP Business Object Web Intelligence
some of the users are more comfortable working in excel and handling detail level of data,
Once we finalize SAP Web Intelligence as our tool based on the business requirement/need ad hoc analysis and interactive reporting
what the expectation of user is to show thousands of rows of detail level data in web intelligence report
Web Intelligence is capable of doing Ad hoc Analysis ->YES, 
Interactive Reporting -> YES ,
Ability to Bring Thousands of Rows of Data -> YES 
But Thinking about practicality How can we navigate thousands/hundreds of pages in Internet Browser
What is the right tool ?
If possible split the requirement to satisfy through SAP Business Objects Analysis edition for Microsoft office for familiar user experience and SAP Web Intelligence for more ad hoc and interactive reporting
Problem 2: Using Crystal reports for data extraction
Some users develop complex crystal report schedule it to folder in file system as excel format (data dump), this data is extracted through macros for another report processing,
What is the right way of doing it?
Data Extraction should be avoided through crystal reports, use intended ETL tool for the Extraction Transformation and Loading in to DB, If Final reporting requirement is pixel perfect, high formatting then crystal report is the right tool
Problem 3: Integrating BO with BEx and need of detailed/granular organization wide data and overcoming data retrieval limitation
(Requirement 1: Need to send summarized values in PDF and do ad hoc analysis)
Some users requires to see detail level of data with all objects in BEx with multi level hierarchy enabled which brings huge volume of data and cause data limit error
Alternative approach
Splitting the Detail data based on key groups and showing summarized data based on groups header, thus avoiding to load all detail data at once
To view the detail level for each group we can use open document linked to each group header, which in turn pass prompts to web Intelligence to display detailed data only relevant to that group and with another open document we can navigate back to crystal reports
Tool Selection
Design Crystal Reports to show summarized data based on key groups or business areas, and
using open document to integrate Crystal reports for Enterprise and SAP BO Web Intelligence
From Crystal reports users can navigate to Web Intelligence to view detail level data for that group by passing prompts
Audience
1) Summarized Data in crystal reports can be scheduled to mail as PDF for Executives
2) Detailed reporting through Web Intelligence can be consumed by Middle Management with some ad hoc analysis
These Problem and Requirement are for example purpose only
Please share/Comment on your Ideas, Problem faced in tool selection and how it is solved so that it will be very useful for Reporting community
I will add it to the list and please do suggest for all BI reporting tools
Use the tool selection guide to choose your reporting tool wisely, think in the shoes of user and also think about right way of doing it
