This zone is used to join the new version of the data, after the time series forecasts are made, with the [dataset](dataset:input_data_lag_values) containing the lag values for each date. 

The [join recipe](recipe:compute_forecasted_ts_features_joined_lag) is made on the reference date column. The reference date column contains the date at which the forecast was made while the date column contains the forecasted date.
