rspec/rules/S3923/abap/rule.adoc

Having all branches in a `+CASE+` or `+IF+` chain with the same implementation is an error. Either a copy-paste error was made and something different should be executed, or there shouldn't be a `+CASE+`/`+IF+` chain at all.

== Noncompliant Code Example

----
IF a >0.
    doSomething.
ELSE IF b> 0.
    doSomething.
ELSE.
    doSomething.
ENDIF.

CASE i.
  WHEN 1 OR 3.
    doSomething.
  WHEN 2.
    doSomething.
  WHEN OTHERS.
        doSomething.
ENDCASE.
----

== Exceptions

Note that this rule does not apply to `+IF+` chains without final `+ELSE+`-s, or to `+CASE+`-s without `+WHEN OTHERS+` clauses.

----
IF a >0.   "no issue, this could have been done on purpose to make the code more readable
    doSomething.
ELSEIF b> 0.
    doSomething.
ENDIF.
