Strange Error in PA

Hi,

I am reading this tutorial : https://github.com/AndreasForster/Predictive/raw/master/SAP_PA_Automated_Tutorial_DataManager.pdf

I am now in page 15 and clicked on "View Data" to see the content of Entity, but I got this error:

2016-04-01 14:34:39 Error Message from ODBC: SQLExecDirect: [S1000][SAP AG][LIBODBCHDB DLL][HDBODBC] General error;260 invalid column name: RKARIMI_DEVUSERCLIENT.CLIENT_ID: line 1 col 38 (at pos 37)

The column CLIENT_ID exist in table and was already selected as the Id field. Moreover, in the tutorial there is DATE_BIRTH column but it does not exist in the data set that I downloaded from Hands-On Tutorial SAP Predictive Analytics, Aut... | SCN.

.Thanks,

Rasoul
