Classification Extractors 1CL_O

My last posting was not clear. I have extended the 2LIS_11_VAITM extractor with a couple of characteristics using transaction code CTBW.

By doing this a DataSource is generated which starts with 1CL_O.

When I create the InfoSource in B/W in the DataSource field the newly created 1CL_O DataSource does not appear.

Any thoughts solutions appreciated thanks
