How to remove Technames in BW objects description

Hello All

We are on SAP BO 4.0 Service pack 4 , Build 738 , and backend BW
7.3. We are building BO reports on Bex queries where BW objects are getting
displayed along with technames appended to each and every object as shown in
below screenshot.

Can any body guide us how to remove these technames BW? as I
don't want to trim then in BO report.
