EDDIE/Web Intelligence Rich Client - References
References are shortcuts to cells whose data you want to reuse.
References have been introduced to provide more flexibility when designing reports. You can use references anywhere in a report or in a formula. As an example, you can use reference to create a summary report that references figures from other reports. At refresh time, references are replaced by the content of their target cells. References can be consumed in an entire document and used for conditional formats or any other calculation.
