IMsProblemCalculationSettings.OutputPeriod

Syntax

OutputPeriod: IMsPeriod;

Description

The OutputPeriod property returns data loading period parameters.

Comments

To set up parameters of problem identification and forecasting, use the IMsProblemCalculationSettings.Period property.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier containing a modeling problem with the PROBLEM_TRANSF_OUTPUT identifier.

Add links to the Metabase, Ms system assemblies.

Sub UserProc;
Var
    Mb: IMetabase;
    MsDescr: IMetabaseObjectDescriptor;
    Problem: IMsProblem;
    CalcSett: IMsProblemCalculationSettings;
    Period: IMsModelPeriod;
    ProblemCalc: IMsProblemCalculation;
    OutPeriod: IMsDatePeriod;
Begin
    Mb := MetabaseClass.Active;
    // Get modeling container
    MsDescr := Mb.ItemById("MS");
    // Get modeling problem
    Problem := Mb.ItemByIdNamespace("PROBLEM_TRANSF_OUTPUT", MsDescr.Key).Bind As IMsProblem;
    // Create problem calculation options
    CalcSett := Problem.CreateCalculationSettings;
    // Load data only by the calendar levels,
    // which are used in the problem calculation chain
    CalcSett.FilterLevelsOnLoad := True;
    // Specify calculation period
    Period := CalcSett.Period;
    Period.IdentificationStartDate := DateTime.Parse("01.01.1990");
    Period.IdentificationEndDate := DateTime.Parse("31.12.2009");
    Period.ForecastStartDate := DateTime.Parse("01.01.2010");
    Period.ForecastEndDate := DateTime.Parse("01.01.2015");
    // Get data loading period parameters
    OutPeriod := CalcSett.OutputPeriod As IMsDatePeriod;
    // Clear parameters of data loading period
    OutPeriod.ClearPeriod;
    // Set autoperiod parameters: data loading period is determined
    // by data loading period of calculated object owner
    OutPeriod.AutoPeriod := MsDateAutoPeriodOptions.StartByFact Or MsDateAutoPeriodOptions.EndAsNow;
    // Set moving of start and end dates for data loading period
    OutPeriod.StartOffset := 1;
    OutPeriod.EndOffset := 2;
    // Perform calculation
    ProblemCalc := Problem.Calculate(CalcSett);
    ProblemCalc.Run;
End Sub UserProc;

After executing the example the problem is calculated by identification, forecasting and data loading determined before the calculation. Data
