On the Forecasting data screen in Change mode, choose Forecast values .

A dialog box appears containing the forecast values calculated by the system.

Change the forecast values as required by entering in the corrected forecast value field the period values on which the next planning run is to be based.

When you choose Enter , the system sets the F (fixing) indicator to show that the forecast values have been fixed and can no longer be changed automatically in subsequent forecast runs.

If you want to fix forecast values without entering corrected values, set the fixing indicator accordingly. Here too, the values will no longer be changed in subsequent forecast runs.
