IValidationMissingMetadata.CalculationType

Fore Syntax

CalculationType: MsCalculationType;

Fore.NET Syntax

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

Description

The CalculationType property determines type of metadata where validation detects missing values.

Comments

Available values:

MsCalculationType.Pointwise. Validation searches for the missing data in observation attribute values.
MsCalculationType.Serie. Validation searches for the missing data in factor attribute values.

Fore Example

Executing the example requires that the repository contains a time series database with the TSDB_VALIDATION_PARAMETERS identifier containing a validation rule with the VALIDATION identifier.

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

Sub UserProc;
Var
    Mb: IMetabase;
    RubrObj: IMetabaseObjectDescriptor;
    ValidObj: IMetabaseObject;
    ValidFilter: IValidationFilter;
    MissingMetaData: IValidationMissingMetaData;
    SelectionAttrValList: IValidationSelectionValueList;
    SelectionAttrFilter: IValidationSelectionFilter;
    Rub: IRubricator;
    MetaAttr: IMetaAttribute;
    ValidMetaAttrs: IValidationMetaAttributes;
Begin
    Mb := MetabaseClass.Active;
    // Get time series database
    RubrObj := Mb.ItemById("TSDB_VALIDATION_PARAMETERS");
    Rub := RubrObj.Bind As IRubricator;
    // Get validation rule
    ValidObj := Mb.ItemByIdNamespace("VALIDATION", RubrObj.Key).Edit;
    ValidFilter := ValidObj As IValidationFilter;
    // Specify that validation is executed by all levels of calendar frequency
    ValidFilter.Level := DimCalendarLevel.None;
    // Specify validation type
    ValidFilter.Kind := ValidationDetailsKind.MissingMetaData;
    // Get parameters of the Missing Metadata validation
    MissingMetaData := ValidFilter.Details As IValidationMissingMetaData;
    // Set type of checked metadata
    MissingMetaData.CalculationType := MsCalculationType.Pointwise;
    // Set checked attribute
    MetaAttr := Rub.Values.Attributes.FindById("CMT");
    ValidMetaAttrs := MissingMetaData.Attributes;
    ValidMetaAttrs.Clear;
    ValidMetaAttrs.Add(MetaAttr);
    // Clear execution area and validation filter
    SelectionAttrValList := MissingMetaData.SelectionTargetData;
    SelectionAttrValList.Clear;
    SelectionAttrFilter := MissingMetaData.SelectionFilter;
    SelectionAttrFilter.Clear;
    // Save changes
    ValidObj.Save;
End Sub UserProc;

After executing the example validation rule of the Missing Metadata type will be set. During its execution the presence of the CMT system attribute value in the factor observation is checked.

Fore.NET Example

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