Hi,
I am having a time series forecasting model.
I set the Historic_ModelCount as 5 and Historic_ModelGap as 5.

But when i try to execute the query(Plz see the PredictTimeSeries
function parameters)


SELECT flattened [Car Name],( SELECT $TIME, [Tot Service Bulletins],
PredictVariance([Tot Service Bulletins]) FROM PredictTimeSeries([Tot
Service Bulletins],-20,-10)) FROM [AHM_ServiceBulletin_Forecase]


I am getting error as follows:

Error (Data mining): A time series prediction was requested with a start
time further in the past than the internal models of the mining model,
AHM_RECALLS_Forecast, specified in the HISTORIC_MODEL_GAP and
HISTORIC_MODEL_COUNT parameters can process.


how i have to specify the parameters for the PredictTimeSeries function.
what r the things i have to consider for that.

plz help me how to specify the range? and what is the erro in the above
query
