Hi,

we are using HANA SPS 10 version and using the PAL ARIMATRAIN for training the prediction model and using ARIMAXFORECAST for prediction with parameter value for "ForecastLength" 3.

we are getting the below error :

Could not execute 'CALL "SCHEMA".PAL_ARIMAXFORECAST_PROC(PAL_ARIMAX_DATA_TBL, PAL_ARIMA_MODEL_TBL, "#PAL_CONTROL_TBL", ...' in 539 ms 614 µs . SAP DBTech JDBC: [423]: AFL error: [423] _SYS_AFL.AFLPAL:ARIMAXFORECAST: [423] (range 3) AFL error exception: exception 73001554: PAL error[73001554]:The length of , is not equal to 3

Getting similar error for even default value of "ForecastLength" 1.

It will be of great help if I could get some help around resolving this error.

thanks,

Shilpa.

Hi Shilpa,

Not sure, whether you found the solution already.

Can you try the "ForecastLenght" value with N (N = number of records in your Data Table or the Model Table)

Regards,

Rajan
