code pal for ABAP > Documentation > Comment Usage Check
This check searches for comments in the code. Clean Code principles do not forbid you to comment your code - but it encourages you to exploit better means, meaningful names and resort to comments only if that fails. Express yourself in code, not in comments.
This check calculates an indicator; precisely, the percentage of comments in relation to the absolute number of real statements (productive code).
Remove unimportant and/or unnecessary comments.
There is no exception for this check since it works as an indicator only. Thus, it is also not possible to suppress its findings.
