The tab is designed as a T-account where the left portion of the account shows the forecasted costs and the right portion shows the forecasted income.
Here you can see a column, diff, which displays the difference between forecast and budget. The Diff column can be edited and then the forecast is changed as well (and vice versa).
Based on the forecasted costs and income, the system calculates contribution margin/contribution ratio as well as the project result. This information is shown at the bottom of this tab.
The forecasted time consumption in hours can be entered for the costs. All cost types except for Material and Subcontracting can have forecasted time consumption.
You can copy a budget to forecast.
