Event Production Management Application

I am working on an application for an event production management company, and am trying to figure out a solution for being able to select a project and have all report views change to the current project.

I was hoping I would be able to set up a criteria function in each Report that would filter fields based on a current project variable, but haven't had success. I found the Global Variables Sample Application, but am not seeing how it would be possible for reports to call for functions.

Does anyone have experience in doing something like this? Is it possible?

Each Project would have

- A Schedule

- Catering Numbers

- Labor Needs

- Equipment Needs

- Etc...

I would like to be able to select a project on an application level, and have that determine the report views. Any help is greatly appreciated!
