IMsLinearDecompositionProblem.Level

Syntax

Level: DimCalendarLevel;

Description

The Level property determines the calendar level that should be used for problem calculation.

Example

Executing the example requires that the repository contains a modeling container with the CONT_MODEL identifier. The metamodel with the META_MODEL identifier must be present in this container. The calendar of the container must begin before 2003, and come to an end after 2010.

Sub Main;

Var

MB: IMetabase;

Cont: IMetabaseObjectDescriptor;

ModelKey: Integer;

CrInf: IMetabaseObjectCreateInfo;

MObj: IMetabaseObject;

Problem: IMsProblem;

LnDecProblem: MsLinearDecompositionProblem;

Period: IMsModelPeriod;

Begin

MB := MetabaseClass.Active;

Cont := Mb.ItemById("CONT_MODEL").Bind;

ModelKey := Cont.Key;

// Create the Problem object

CrInf := Mb.CreateCreateInfo;

CrInf.ClassId := MetabaseObjectClass.KE_CLASS_MSPROBLEM;

CrInf.Id := "New_ForwardLookingProblem";

CrInf.Name := "New_ForwardLookingProblem";

CrInf.Parent := Cont;

CrInf.Permanent := False;

MObj := Mb.CreateObject(CrInf).Edit;

Problem := MObj As IMsProblem;

// Add the metamodel

Problem.MetaModel := MB.ItemByIdNamespace("META_MODEL", ModelKey).Bind As IMsMetaModel;

// Determine the problem type - Forward-looking forecasting

LnDecProblem := New MsLinearDecompositionProblem.Create;

Problem.Details := LnDecProblem;

// Determine a calendar level on which calculation of a problem is executed

LnDecProblem.Level := DimCalendarLevel.Month;

// Determine parameters of the periods on which calculation of problem is executed

Period := LnDecProblem.Period;

Period.IdentificationStartDate := DateTime.ComposeDay(2003, 1, 1);

Period.IdentificationEndDate := DateTime.ComposeDay(2007, 12, 31);

Period.ForecastStartDate := DateTime.ComposeDay(2008, 1, 1);

Period.ForecastEndDate := DateTime.ComposeDay(2010, 12, 31);

MObj.Save;

End Sub Main;

After executing the example, a new problem of the Forward-Looking Forecasting type with the New_ForwardLookingProblem identifier is created in the modeling container. The metamodel is added to the problem, the level of a calendar and parameters of the periods necessary for calculation of a problem are determined.
