Thanks for your help.
Currently, I'm working on a web consoel report, which can be look cool, and more up to date than a legacy report.
But, I'm still trying to deal with the individual generate process of report, which seem even more difficult with web console report.
I'm also looking into the Worskflow, hope it will avoide me of creating 1600 schedule of report creation.
Hope to find a solution, steal searching.
