How To Fix RSDME304 - Kein gültiger Entscheidungsbaum aufgebaut

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDME -

• Message number: 304

• Message text: Kein gültiger Entscheidungsbaum aufgebaut

Was verursacht dieses Problem?

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

Systemantwort

Das System gibt eine Fehlermeldung aus und erlaubt Ihnen nicht, mit dieser Transaktion fortzufahren, bis der Fehler behoben ist.

Wie behebe ich diesen Fehler?

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.
