== Why is this an issue?

Using ``++EXIT++`` and ``++CHECK++`` in ``++SELECT++`` statements to stop the execution of ``++SELECT++`` loop is an expensive and ineffective way to filter data. Filtering should be part of the ``++SELECT++`` loop themselves. Most of the time conditions located in a ``++CHECK++`` statement should be moved to the ``++WHERE++`` clause, and the ``++EXIT++`` statement should typically be replaced by an ``++UP TO 1 ROW++`` clause.


=== Noncompliant code example

[source,abap]
----
SELECT * FROM SBOOK INTO SBOOK_WA.
  CHECK: SBOOK_WAS-CARRID = 'LH' AND SBOOK_WAS-CONNID = '0400'. "Noncompliant
ENDSELECT.
----


=== Compliant solution

[source,abap]
----
SELECT * FROM SBOOK INTO SBOOK_WA WHERE CARRID = 'LH' AND CONNID = '0400'.
ENDSELECT.
