The code contains too many unchecked returns of functions calls
Why you should care
Missing return code checks after an Open SQL statement can result in unpredictable behavior and untraceable execution errors. This is why it is extremely important to report and handle errors as soon as they occur.
CAST Recommendations
Check the system field SY-SUBRC after SQL commands, internal table commands and file-handling commands.
