Now that your upload is done, you have the option to compute all your data at once.

All you have to do is go to Forecast Edition. Check that you do not have any aggregated fields (if necessary remove the aggregation using the Aggregation fields... button).

Then you just have to click on the calculator icon, circled in red below.

Next, you will see a pop-up window. Make sure Forecast for all SKUs is selected. Then click on Confirm & Launch to obtain new forecasts, based on your latest data, and an update of your ABC classes, assuming this latter option is selected.

A series of jobs is then performed by the platform. When your number of jobs (in the top right section) goes back to green status, this means all your data have been computed. You can navigate the tool during the computation, which may take some time according to the number of items to be processed.
