BEx Query Transport

Hi,

I want to transport Bex query which I modified but I don't want to transport any variable associated with the query. When I click on "Query Element" check box, it selects all the objects underneath it including variables and I don't want to manually uncheck any box as there are chances I may or may not select any object that i don't want to transport.

I know if I check the query name check box (highlighted in red in below screenshot) then I can only select the objects I need to transport but the check box highlighted in red is grayed out

How can i select the check box in front of my query (highlighted in red) why is it grayed out, will appreciate your help, thanks.Regards
