Como genero informes de los procesos

Tengo implementado un proceso pero no puedo generar informes de los casos ingresados.

Sorry but can you be a little bit more specific about what kind of information you want to display?

Also are you familiar with the difference between forms (used in processes) and pages (used to build applications)?
Note that different type of forms exist: form to start a new process instance (i.e. instantiation form), form to perform a task and overview form to display information (read-only) about a process instance at any time (including information about the process instance but also business variables).
