How to get the BEx query from the WEBI report

Gurus,

What is the easiest and fastest way of finding out the BEx query related to a particular webi report? I understand I can find the universe on which the WEBI is and then check the connection for the Universe and get the query for the connection but is there some faster way or more direct way of getting to the source?

Say if I know the CUID of the WEBI is there a direct way of getting the complete meta data for this all the way to the BEx query?

Thanks
