== Why is this an issue?
|
|
|
|
The requirement for an ``++OTHERS++`` clause is defensive programming. The clause should either take appropriate action, or contain a suitable comment as to why no action is taken.

=== Noncompliant code example

[source,abap]
|
|
----
|
|
CASE SY-INDEX. // Noncompliant; missing WHEN OTHERS clause
|
|
WHEN ONE.
|
|
WRITE 'One'.
|
|
WHEN 2.
|
|
WRITE 'Two'.
|
|
ENDCASE.
