PAL error[73001273]:C45 supports only classification, not regression

158 Views

Hi,

im trying to run the code example from the SAP HANA PAL Library.

https://help.sap.com/viewer/2cfbc5cf2bc14f028cfbe2a2bba60a50/2.0.01/en-US/e1acc4e6d75e46af8aea0cbeba01eaca.html

The Scenario is using three codes. The first code with the K-Means runs perfectly fine, but now I'm stucked with the second code, where you have to build the C4.5 Decision Tree Model.

When I'm trying to run the following Code:

CALL DM_PAL.PAL_CREATEDT_PROC(PAL_KMEANS_RESULT_TBL, "#PAL_CONTROL_TBL", PAL_CDT_JSONMODEL_TBL, PAL_CDT_PMMLMODEL_TBL) WITH OVERVIEW;<br>

I get following error message:

SAP DBTech JDBC: [423]: AFL error: search table error: _SYS_AFL.AFLPAL:CREATEDTWITHC45: [423] (range 3) AFL error exception: exception 73001273: PAL error[73001273]:C45 supports only classification, not regression

Does anyone know, what I have to change to run Code successfully?
