If you create a decision tree that includes a node containing more than 1,500,000 observations and pruning is turned on, an error similar to the following might be issued:

This problem can occur when either SAS® Visual Statistics or the IMSTAT Procedure in SAS® In-Memory Statistics is used to create the decision tree.
To circumvent this problem, turn off pruning.
