IMsFormulaTransform.OutputPeriod

Syntax

OutputPeriod: IMsPeriod;

Description

The OutputPeriod property returns data loading period parameters.

Comments

To set up parameters of model calculation period, use the IMsFormulaTransform.Period property.

Example

Executing the example requires that repository contains modeling container with the MS identifier. The container must contain metamodel with the METAMODEL_TRANSF_OUTPUT identifier including model with the MODEL_TRANSF_OUTPUT identifier to the calculation chain.

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

Sub UserProc;
Var
    mb: IMetabase;
    MsKey: Integer;
    MetaModel: IMsMetaModel;
    pParams: IMsModelParams;
    pPar: IMsModelParam;
    pModel: IMsModel;
    pPeriod: IMsDatePeriod;
Begin
    // Get current repository
    mb := MetabaseClass.Active;
    // Get modelling container key
    MsKey := mb.GetObjectKeyById("MS");
    // Get metamodel
    MetaModel := mb.ItemByIdNamespace("METAMODEL_TRANSF_OUTPUT", MsKey).Edit As IMsMetaModel;
    // Get metamodel parameters
    pParams := MetaModel.Params;
    // Remove all parameters
    pParams.Clear;
    // Add metamodel parameter to set start of data downloading period
    pPar := pParams.Add;
    pPar.Id := "OUT_START";
    pPar.Name := "Data downloading start";
    pPar.DataType := DbDataType.Date;
    pPar.DefaultValue := DateTime.Parse("01.01.2018");
    // Add metamodel parameter to set data downloading period end
    pPar := pParams.Add;
    pPar.Id := "OUT_END";
    pPar.Name := "Data downloading end";
    pPar.DataType := DbDataType.Date;
    pPar.DefaultValue := DateTime.Parse("01.01.2020");
    // Save changes of the metamodel
    (MetaModel As IMetabaseObject).Save;
    // Get the model
    pModel := mb.ItemByIdNamespace("MODEL_TRANSF_OUTPUT", MsKey).Edit As IMsModel;
    // Get model calculation period parameters
    pPeriod := pModel.Transform.OutputPeriod As IMsDatePeriod;
    pPeriod.ClearPeriod;
    // Set model parameters determining start and end of data downloading period
    pPeriod.StartParam.Parameter := pParams.FindById("OUT_START");
    pPeriod.EndParam.Parameter := pParams.FindById("OUT_END");
    // Save changes in the model
    (pModel As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the start and end of the model data loading period will be set by the OUT_START and OUT_END parameters.
