IExpression.References

Syntax

References: String;

Description

The References property determines the list of units/forms containing the custom functions that are used to create an expression.

Comments

Identifiers of units/forms in the list are separated by the ";" symbol. All the functions contained in these units and used to create an expression must be declared with the Public modifier.

Example

Executing the example requires a calculated cube with the Virt_Cube identifier and the Module_1, Module_2 units containing the custom functions MyFunc, MyFunc1. These functions calculate values for the specified cube coordinates.

Sub UserProc;
Var
    MB: IMetabase;
    CCI: ICalculatedCubeInstance;
    Coo: ICalculatedCubeInstanceCoord;
    Formulas: ICalculatedCubeFormulas;
    Formula: ICalculatedCubeFormula;
    Expr: IExpression;
    i: Integer;
Begin
    Mb := MetabaseClass.Active;
    CCI := Mb.ItemById("Virt_Cube").Open(Null) As ICalculatedCubeInstance;
    Coo := CCI.CreateCoord;
    For i := 0 To Coo.MatrixCoord.Count - 1 Do
        Coo.MatrixCoord.Item(i) := 0;
    End For;
    Formulas := CCI.Formula(Coo);
    Formula := Formulas.Item(0);
    Expr := Formula.Expression;
    Expr.References := "Module_1;Module_2";
    Expr.AsString := "MyFunc-MyFunc1";
    Formulas.Save;
    CCI.SaveFormulas;
End Sub UserProc;

After executing the example one formula is added in the calculated cube by the specified coordinate. The formula expression will use the custom functions contained in the Module_1 and Module_2 units.
