i have some questions about forecast management. According to best practice scenario J11 is seems there are two ways for making forecast:
1) app "plan customer projects" using calendar at work package level in which i can change the hours and the system updates costs and revenues
2) app "review customer projects" filling the effort to complete per each work item . In this case the system updates the POC of the project but not the plan present in point 1) at WP level
Which is the correct one or there is another way o app to make forecast?
How version are managed?
Is it possibile to make a forecast of the expenses for each mounth?
Is it possible to make a revenue forecast for quarter?
Thanks a lot in advance.
