This process is used to prepare and make calculations for forecasting expected values. The values can be specified for separate accumulator fields in datasets. This is for periodic forecasting, most suitably at the beginning of a new period when the actual results from the previous period are completed.
Transaction type 34 (Sales forecast) is available in a dataset for reporting purposes after using this process.
In M3 Sales forecasting there are two ways of forecasting: standard forecasting and advanced forecasting. The difference between these two types is that the following issues are available in advanced forecasting:
Another difference is that in standard forecasting, forecast on a field, e.g invoiced quantity (UCIVQT), is based on the historical data of the same field (UCIVQT). The demand used in advanced forecasting is instead based on other fields. This is further described below.
Checking forecast method and parameters
To start the process, the forecast methods and parameters for the dataset to be forecasted must be checked and changed, if necessary. This is done in 'Sales Forecast Method. Open' (OSS430).
When forecasts are generated using forecast simulations, the simulation forecasts methods used must also be checked and/or changed. This is done in 'Sales Forecast Method. Connect Competing' (OSS431), which is called using option 11 = Forecast sim from 'Sales Forecast Method. Open' (OSS430).
The dataset should also be checked to ensure the correct forecast method and forecasted accumulator fields are selected and matched.
The forecast calculation is done automatically for every dataset selected using the selected forecast methods. Forecast calculations for separate datasets can also be done in 'Sales Forecast. Generate in Dataset' (OSS440).
