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.

Hi prokopp80,

thanks a lot for reporting this bug. The issue here is that FINAL is a rather new keyword (introduced with ABAP release 7.57), and if it is used, the SELECT statement has to follow the "strict mode" rules of that release. This one doesn't, because for that, UP TO 1 ROWS would need to be positioned after the INTO clause.

Strict mode rules are no trivial topic, and unfortunately, some of them cannot be checked by ABAP cleaner due to missing backend access. However, I tried to cover some important cases, so with the next release, "Use FINAL for immutable variables" will identify your example as non-strict (and refrain from introducing FINAL into it), while it will still use FINAL in the modified code:

Kind regards,
