Decision Tree training runtime error. Perform Pruning.
Hello I get the error below when trying to train a decisio n tree model in RSANWB. The same model trained correctly before I selected Perform Pruning + Extended Pruning in the Parameters tab.
Note 738285 seems to address a similar problem, but is not applicable (or already corrected) in the system I am running (SAPKW35012, SAPKIBIFP5).
Can anyone help me on that?

Here is the error log.
