Thanks for your reply. That was what this person said that GLOBAL can be used across multiple reports. I have never seen any where that could be the case, even if you use the Repository. Is that what you are saying that GLOBAL variables can be used between two different reports?
"takes less resources to manage variables within a single report than across multiple reports"
I dont see how that could be possible.
As for resources, I will have to create a couple of reports, one with GLOBAL variables and one with SHARED variables and see if there is any resource difference. I will let you know what I find out.
