Predictive analytics Forecast service

[Former Member]

Hi,

We have created the table with fields Temperature,Pressure and Date. Requirement is to forecast the temperature value. We have inserted 300+ data's for the table and we have successfully registered the data set. With the data set ID we tried to run the forecast service in synchronous mode with date column as :Date" and target column as "temperature". But we are getting the following error

{ "errors": [ { "errorCode": "EXX114", "errorMessage": "An internal error has occurred : The training data set does not contain enough values for the\nextra-predictable variables to cover the number of requested forecasts." } ] }

May I know what is the minimum number of records we need to predict the values or the other possibilities to get the above error.

We are following the blog " https://www.sap.com/developer/tutorials/hcpps-rest-ps-forecast.html "

PFA for the issue.

Hi suriya_chidambaram & prashanth_d,

I missed your comments as you didn't mentioned me using the "at sign".

As per the doc, the EXX114 relates to an error that occurred while training a data mining model. <submessage> refers to an error message raised by the predictive model engine.

This means that the predictive service cannot access your data most likely. Did you create the table using the same database user as the one used by the predictive service (in the datasource binding).

Can recreate your table with the database user used by the predictive service datasource binding?

Thanks
