Cause of the message
If there is not enough data to create a prediction model, the training process cannot proceed.
Solution
Import prediction model creation (training) data that contains at least 11 rows.
Some prediction types require more data.
Also, if the data count included in the prediction model creation (training) data is too low, the performance of the prediction model may not improve.
For the relation between the amount of data and predictive performance, see Tips How to Create a Dataset.
