The model is in Adding an Aggregated Forecasting Model (Intermediate Data Mining Tutorial).I am trying Building Forecasting Scenario and there are 12 regions,time and sales quantity for each region. I then sum the quantities
and get all regions sales in one column and created the forecasting model. I then applied this model to T1000 Pacific region but below is the error message that I received:
TITLE: Microsoft SQL Server 2008 R2 Analysis Services ------------------------------
Error (Data mining): Data associated with the key value, 'T1000 Pacific', was not used during training and because this, the value is not a valid key.
