AbapCleaner does change the below block to use @FINAL(...) instead of @DATA(...) which is not syntaxtically correct

[prokopp80]

Before:
SELECT werks FROM t001k AS b INNER JOIN t001w AS p ON bbwkey = pbwkey UP TO 1 ROWS INTO @DaTa(lv_werks).
ENDSELECT.

After:
SELECT werks FROM t001k AS b INNER JOIN t001w AS p ON bbwkey = pbwkey UP TO 1 ROWS INTO @Final(lv_werks).
ENDSELECT.

the latter one is not correct.
