Forecast Versions (SAP Library - Forecasting (LO-PR))

Forecast Versions

By saving many versions of the forecast for one key figure and characteristic values combination, you can compare, for example, forecasts based on different models but using the same historical data, or forecasts with corrected and uncorrected historical time series.

In consistent planning, forecast versions are saved at the detailed level only.

In level-by-level planning, forecast versions are saved at the level on which you create them.

This function is not available with delta planning.

To access the forecast versions of a product group, material, or other characteristic value, choose Versions in the model selection dialog box. For each version, you see:

The date on which the forecast was run.

The version’s history number.

The version numbers show you the sequence in which forecast versions based on this forecast model were created.

The version number of the forecast profile, that is, of the forecast parameters.

Each forecast profile has its own version number. The combination of history number and forecast profile version number uniquely identifies a forecast version.

The description of the forecast profile.

The status of the forecast profile.

Status 1 designates the last version to be copied to the planning table.
Status 2 designates the last version to be saved but not copied to the planning table.
A blank designates any older version that was saved or copied to the planning table.

To copy a previously saved forecast version into the planning table, select the version you want to copy in the Versions dialog box and then use the Choose and Copy results pushbuttons.

To delete one or more forecast versions in the background, choose Planning ® Mass processing ® Reorg. forecast. You can opt to delete one or more forecast versions based on a particular forecast model (that is, a particular combination of forecast parameters). You can also delete individual forecast versions online, by choosing Versions and Delete in the forecast dialog box.

By setting the indicator Do not save to forecast DB, you can switch off the use of forecast versions. You set this indicator by choosing Set parameters of info structures and key figures in Customizing. The forecast results are then saved in the information structure but not in the forecast database. Therefore, if you run the forecast and copy the results to the planning table, any previous forecast results are lost. The advantage of setting this indicator is that you achieve performance improvements.
