If you have set that Sales Forecast is to be based on "Omsättning från framtidsfrågor" / "Turnover from future questions", this means that Forecasts for sales are calculated on what is entered on the page "Future questions" / "Framtidsfrågor". Alternatively, the information has been loaded from the so-called Intagsblankett / Admission Form (excel form)
Should it be the case that no information has been entered on the page "Forecast simple" regarding Sales, the program must still create a forecast so that it does not become empty for the item Sales. This means that you must select a "Secondary" forecast that takes over if no data has been entered / loaded on the page "Forecast simple" and Sales (see more in Prognos / Forecast).
The choices available for secondary forecast are the same as for other items in the income statement and balance sheet (linear, weighted rolling average, etc.).
