Hi guys!!
Got it!!!
if you look at OSS note 1460199 - Creating datasource for article classifications, you will get the answer
Actually, when creating the DS, at the generation step, the systems may ask you :
The selected class type is a variant class type.
It contains both the configuration data and the classification data.
Generate DataSource for Configuration Data? (When you choose "No", the system creates the DataSource for the classification data).
If you want the data and not the global configuration information, choose NO
Then, you are in business!!
