IMsModelPeriod.AllowForecastBeforeIdent

Syntax

AllowForecastBeforeIdent: Boolean;

Description

The AllowForecastBeforeIdent property determines whether forecasting period is available before sample period.

Comments

Available values:

True. Forecasting period can be before sample period.
False. Forecasting period can be only after sample period.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier containing a model with the MODEL_FREEDIM identifier.

Add links to the Metabase, Ms system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Model: IMsModel;
    Period: IMsModelPeriod;
Begin
    // Get current repository
    MB := MetabaseClass.Active;
    // Get the model
    Model := MB.ItemByIdNamespace("MODEL_FREEDIM", MB.ItemById("MS").Key).Edit As IMsModel;
    // Get model periods
    Period := Model.Transform.Period;
    // Determine that forecasting period can be before sample period
    Period.AllowForecastBeforeIdent := True;
    // Set sample period dates
    Period.IdentificationStartDate := DateTime.ComposeDay(2005, 1, 1);
    Period.IdentificationEndDate := DateTime.ComposeDay(2015, 12, 31);
    // Set forecasting period dates
    Period.ForecastStartDate := DateTime.ComposeDay(2000, 1, 1);
    Period.ForecastEndDate := DateTime.ComposeDay(2004, 12, 31);
    // Determine that on modeling problem calculation model periods are used
    Model.UseModelPeriod := True;
    // Save changes
    (Model As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the forecasting period, which is before sample period, is set for the model.
