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 @bdel

As per your suggestion we have created the table with only "date" and "temperature" column and without any extra predictors. When we register the dataset and tried to run the forecast service in Postman,we face the error as per the attached screen shot exx114.png.

Please suggest.

Thanks in advance,

Hi Suriya,

Can you share the dataset description for datasetID 42? It seems that this error is linked to the dataset description.

Thanks
