Improve opportunity reporting
There are few problems with the opportunity reporting:
- it is based only on start date
- it does provide trend (like sale reporting)
- it does not follow the same design as sale reporting
Indeed the reporting should be divided in two kind. The first using the start date is more about lead with counting, amount and the conversions. The second is about statistics for the conversion which should be based on the end date about winning and losing number and amount. By using the same design as sale reporting, we can also add trend to each field.
