IMsCalculationChainGroup.CalculationType

Fore Syntax

CalculationType: MsCalculationType;

Fore.NET Syntax

CalculationType: Prognoz.Platform.Interop.Ms.MsCalculationType;

Description

The CalculationType property determines a mode of calculation of group.

Comments

By default, the group is calculated in the series mode, that is, CalculationType = MsCalculationType.Serie.

The property is relevant if the calculation of the group is executed by the transformation problem.

NOTE. If the group uses parameters, dynamic changes are not taken into account on calculation.

Fore Example

Executing the example requires that the repository contains a modeling container with the MODEL_SPACE identifier. This container contains a metamodel with the METAMODEL identifier and a model with the MODEL identifier.

Add links to the Dimensions, Metabase, Ms system assemblies.

Sub UserProc;
Var
    Metabase: IMetabase;
    ModelspaceDescr: IMetabaseObjectDescriptor;
    MetaModel: IMsMetaModel;
    CalculationChain, FolderCont: IMsCalculationChainEntries;
    Folder: IMsCalculationChainFolder;
    Period: IMsModelPeriod;
    Model: IMsModel;
    CalcModel: IMsCalculationChainModel;
Begin
    Metabase := MetabaseClass.Active;
    // Get modeling container
    ModelspaceDescr := Metabase.ItemById("MODEL_SPACE");
    // Get metamodel
    MetaModel := Metabase.ItemByIdNamespace("METAMODEL", ModelspaceDescr.Key).Edit As IMsMetaModel;
    // Get metamodel calculation chain
    CalculationChain := MetaModel.CalculationChain;
    // Clear calculation chain
    CalculationChain.Clear;
    // Add a folder to calculation chain
    Folder := CalculationChain.AddFolder("Source data");
    // Set calendar level to calculate folder
    Folder.Level := DimCalendarLevel.Year;
    // Set calculation period of folder
    Period := Folder.Period;
    Period.ForecastEndDate := DateTime.Parse("01.01.2015");
    Period.ForecastStartDate := DateTime.Parse("01.01.2010");
    Period.IdentificationEndDate := DateTime.Parse("31.12.2009");
    Period.IdentificationStartDate := DateTime.Parse("01.01.1990");
    // Set mode of folder calculation
    Folder.CalculationType := MsCalculationType.Pointwise;
    // Form folder contents
    FolderCont := Folder.Contents;
    // Get model
    Model := Metabase.ItemByIdNamespace("MODEL", ModelspaceDescr.Key).Bind As IMsModel;
    // Add model to folder
    CalcModel := FolderCont.AddModel(Model);
    // Specify that model inherits parameters of calculation period from folder
    CalcModel.InheritModelPeriod := True;
    // Save changes
    (MetaModel As IMetabaseObject).Save;
End Sub UserProc;

Example execution result: the folder, which contains metamodel is added to the metamodel chain. The folder is a group of elements and the following will be set for it: calendar level and calculation period, calculation mode. The model, which is contained in the folder, inherits the calendar level and the folder calculation period.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.
