How to find out which connection is used for access to Bex query?

Hello,

in our BO 4.0 environment we have a lot of different connections to Bex queries.

There exist more connections to one Bex query.

For example to Bexquery1  we can access with 2 connections, connection : BX1 (connection specific for one query) and connection DEVcubes(generic connection to all cubes)

How can I check in Webi report over Bex query which connection is currently used?

Thanks a lot !
