Hi Ronny,
At this point in time, Blob and Clob are not supported in CA 2E. There are currently no plans to support them. If you/others desire this functionality. I would suggest to raise an 'Idea' (under the 'Actions' dropdown) on the Idea Wall and vote/comment on it amongst the customer community, so that it can garner enough votes to make it to backlog.
Thanks!
Steve
