IMsMetaAttributeValues.Selection

Syntax

Description

The Selection property determines the element selection.

Example

Executing the example requires a time series database with the OBJ_RUBRICATOR identifier. COUNTRY is the custom attribute of time series database that refers to the dictionary.

Sub Main;

Var

ActiveMetabase: IMetabase;

Ruby: IRubricator;

Transform: IMsFormulaTransform;

TransformVar: IMsFormulaTransformVariable;

Coord: IMsFormulaTransformCoord;

Slice: IMsFormulaTransformSlice;

Selector: IMsFormulaTransformSelector;

Formula: IMsFormula;

Det: IMsDeterministicTransform;

Term: IMsFormulaTerm;

TermInfo: IMsFormulaTermInfo;

MetaAttr: IMetaAttribute;

MetaVals: IMsMetaAttributeValues;

Dict: IMetabaseObject;

DI: IDimInstance;

Sel: IDimSelection;

Dict := MetaAttr.ValuesObject.Bind;

DI := Dict.Open(Null) As IDimInstance;

Sel := DI.CreateSelection;

Sel.SelectElement(0, False);

MetaVals.Selection := Sel;

TransformVar := Transform.Inputs.Add(Null);

Slice := TransformVar.Slices.Add(Null);

Term.TermInfo := TermInfo;

Det.Expression.AsString := Term.TermToInnerText;

Executing this example creates an object that contains calculation parameters for series of the time series database.
