IMsModelPeriod.IdentificationStartDateCoord

Syntax

IdentificationStartDateCoord: IMsModelCoordAttributes;

Description

The IdentificationStartDateCoord property determines settings of the coordinate that sets sample period start date.

Comments

The coordinate is available only if the model is in the multidimensional iterator. In calculation, the coordinate is the current iteration of multidimensional iterator, in which the model is calculated.

Example

Executing the example requires that the repository contains a modeling container with the MODEL_SPACE identifier. A problem with the PROBLEM identifier and a metamodel, to which multidimensional iterator is added, are created in the container. One model is included in the multidimensional iterator. A data source for the model includes the dimension, which includes attributes with the STARTDATE and ENDDATE identifiers. Dates are stored as attribute values.

End Sub UserProc;

After executing the example sample, forecasting and data loading periods are changed for the model. Period values are taken according to the current iterator iteration and created by values of specified dimension attributes.
