Reporting - get report from two or more modules ex. Meetings , Calls and Tasks in one Report viw

Can I have a Report from AOR to include data from Meeting , Calls and Tasks .
I have a customer request to Get Salesman as a Group and underneath to include all Activities of that Salesman for the previous Week .
Activities include Meetings , Calls, Task ( she also wants newly Leads created) , withing the Last Week.

Can I have a Report build upon a View that I can create in the database and not based on Specific module ?
A UNION query, can handle such a report. With common comumns .

Lias

Hola Lias, ¿conseguiste desarrollar el informe?
Tengo que hacer algo parecido y estoy bastante perdida, soy nueva en esto y mis conocimientos bastantes limitados. Muchas gracias
