+The rule finds the use of the `FindByName`, `FindByCode` or `FindByNumber` methods using specific numbers, codes and names of elements or documents. 
+Similar code may not work correctly in other databases.
+Often such code is test code included in the release version, which is also not recommended.
+
+It is recommended to specify constant data values ​​from the database in "Сonstants" or predefined metadata elements.
