As we all know, Bex variables are very useful and usually are widely used.
The problem is that when we want to change a variable, it may affect lots of queries and users.
We
had an issue when we needed to change a variable from Mandatory to
Optional, (In order not to display Variable screen in WAD), and we
wanted to update all dependant queries/users with the change.
In order to find all dependant queries we used the next technique.
The way to get that list is to go into "Transport connection" in RSA1
