Description

The AllowForecastBeforeIdent property determines whether forecasting period can be before sample period.

Comments

Available values:

True. Forecasting period can be before sample period.
False. Forecasting period must be after sample period.

Example

Executing the example requires a workbook with the WB_AUTOPERIOD identifier containing a calculated series. This series must be the first in data table and must be calculated by means of forecasting method.

Add links to the Cubes, Express, Laner, Metabase, Ms system assemblies.
