We have a professional services operation. I'm trying to figure out how to generate a report for out billing department that shows the amount of time billed (or logged) for a specific project within a certain time frame. The Time Log report will not work, since it does not allow for the propagation of custom fields that are in use as Project Identifiers. Plus, billing doesn't care which person did which work on which day; they just care about how much time was billed last month.
In short I need to create a Project report that shows how much Time was Spent last month. In the Report, I would need the Project name, the Time Spent for a time period and a few custom fields.
