A loop with at most one iteration is equivalent to the use of an IF statement to conditionally execute one piece of code. No developer
expects to find such usage of a loop statement. If the initial intention of the author was really to conditionally execute one piece of code, an
IF statement should be used in place.
At worst that was not the initial intention of the author and so the body of the loop should be fixed to use the nested STOP,
RETURN or EXIT statements in a more appropriate way.
Noncompliant code example
DATA remainder TYPE i.
DO 20 TIMES.
remainder = sy-index MOD 2.
cl_demo_output=>write_text().
EXIT. " noncompliant, loop only executes once
ENDDO.
Compliant solution
DATA remainder TYPE i.
DO 20 TIMES.
remainder = sy-index MOD 2.
cl_demo_output=>write_text().
ENDDO.
