When scenery is an advantage (5)

Ross

I believe the answer is:

asset

'an advantage' is the definition.
(I've seen this before)

'when scenery' is the wordplay.
'when' becomes 'as' ().
'scenery' becomes 'set' (a stage set).
'as'+'set'='ASSET'

'is' acts as a link.

(Other definitions for asset that I've seen before include "A useful thing l" , "Something valuable to have" , "one liable to be stripped?" , "Useful thing or person" , "Help" .)

I've seen this clue in The Telegraph.
