IMsVariable.Execute

Syntax

Execute(Settings: IMsVariableLoadSettings);

Parameters

Settings. Settings that are necessary to load the data to the variable by formula.

Description

The Execute method loads data to the variable.It is used on data loading by means of the formula.

Example

Executing the example requires that the repository contains a modeling container with the Kont_Model identifier. The container includes a modeling variable with the Var_1 identifier.

After executing the example a modeling variable is created in the modeling container. The way of data filling is by formula. Two levels are presented in the variable frequency. They are Years and Half-years. For the Years level of calendar the aggregation is set: Half-year level data is summed. For formula composing one variable is added. The lag and transformation are set, after that the formula is composed. For specified period the data is loaded to the variable by the Fact dimension.
