Material Classification not working properly

Hi Gurus,

I am currently working on material classifications and have some issue in it.

Things I have read and tried out:

Classifications are very specific to every Client and are cross application. This can be done via transaction CTBW, by specifying client number, class type, data source name, fields and etc. values. Then we need to generate data source for the same.

Issue:

When I generate the data source in CTBW and check the data in RSA3. I am not able to get any data.

Please help, as it a very urgent issue and I am feeling stuck. I also tried to Google the same but did not get any good and relevant document or any post.

Regards,

Sourabh Deo
