Active reports creation for customers

[cognos05]

Hi All,

I have around 40 different customers and data related to them, like reps under them and accounts under them.

In cognos, I create one report with say a level Distributor and it automatically filters my report.

I understand active report is a kind of saved .mht file.

If I want to create active reports, I came to know that we need to do report bursting  based on customers.
My approach is to create one report with levels like distributor, customers and use them in report and then burst it,

But when I run this report with generic levels instead of hardcoding specific distributor , the data is more and it doesnt load..

Can I still burst the report without running,
Suggestions on how to go ahead.

Thanks,
Nithya
