ICalculatedCubeFormulas.Item

Syntax

Item(Index: Integer): ICalculatedCubeFormula;

Parameters

Index. Formula index.

Description

The Item property returns the formula, which index is passed by the Index parameter.

Comments

There is at least one formula by each coordinate. If the cube has the dimension that controls selection of formula actual period, formulas for various periods are added by the Add method.

Example

Executing the example requires that the repository contains a calculated cube with the Calc_Cube identifier. The source cube and the calculated cube contain two dimensions that are not fixed.

Sub UserProc;
Var
    MB: IMetabase;
    CubeInst: ICalculatedCubeInstance;
    Coord, SourceCoord: ICalculatedCubeInstanceCoord;
    Formulas: ICalculatedCubeFormulas;
    Formula: ICalculatedCubeFormula;
Begin
    MB := MetabaseClass.Active;
    CubeInst := MB.ItemById("Calc_Cube").Open(NullAs ICalculatedCubeInstance;
    //Get coordinate in calculated cube
    Coord := CubeInst.CreateCoord;
    Coord.MatrixCoord.Item(0) := 0;
    Coord.MatrixCoord.Item(1) := 0;
    //Get coordinate from source
    SourceCoord := CubeInst.CreateSourceCoord(CubeInst.Sources.Item(0));
    SourceCoord.MatrixCoord.Item(0) := 0;
    SourceCoord.MatrixCoord.Item(1) := 0;
    //Get formulas
    Formulas := CubeInst.Formula(Coord);
    Formula := Formulas.Item(0);
    Formula.Expression.AsString := SourceCoord.AsTerm + "*3.14";
    Formulas.Save;
    CubeInst.SaveFormulas;
End Sub UserProc;

After executing the example a formula is set by the specified cube coordinate. A term that refers to appropriate coordinate in the source cube is used in the formula expression.
