SAP Error Message - Details

• Message type: E = Error

• Message class: RSDME -

• Message number: 304

• Message text: Aucun arbre de décision valide créé.

Quelle est la cause de ce problème?

The data used for training does not contain sufficient or the required
information to form a decision tree. This could be due the following
reasons:
Model parameters like <ZK>Min. Leaf Cases </>or <ZK>Leaf Node Accuracy
</> are set to very high values
Specified model fields in the model have no strong relation with the
predictive model field values
The data has too many missing values

Réponse du système

Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.

Comment corriger cette erreur?

Change model parameter values and perform training.
If there are some fields in the data that could have an effect on the
prediction model field value, include these fields in the model
definition (if they are not already included). Perform training again.
If you have used pruning, deactivate it and re-train the model. The
resulting tree may be prone to over-fitting and hence may not be
accurate.
If you have tried all of the above and you still do not obtain a valid
decision tree, this implies that the data you are using is not fit for
decision tree training.
