A configuration example of the forecast length estimator using an external forecast time series is given below:

The logging will provide you with the information which forecast length was used in the run, see example below

Here is a configuration example of the forecast length estimator using a simulated forecast time series. Make sure that your are using the read write mode "read complete forecast" or define a relative view period instead.

The endoverrulable attribute in the relative view period in time series sets must be set to true in all subsequent modules in which you want to use the actual forecast length. |
