tWarn
Triggers a warning often caught by the tLogCatcher component for exhaustive log.
Both tDie and tWarn components are closely related to the tLogCatcher component. They generally make sense when used alongside a tLogCatcher in order for the log data collected to be encapsulated and passed on to the output defined.
This component provides a priority-rated message to the next component. It does not stop your Job in case of error. If you want to kill a Job in case of error, see the tDie documentation.
tWarn Standard properties
These properties are used to configure tWarn running in the Standard Job framework.
The Standard tWarn component belongs to the Logs & Errors family.

WARN_MESSAGES: the warning message. This is an After variable and it returns a string. WARN_CODE: the code level of the warning message. This is an After variable and it returns an integer. WARN_PRIORITY: the priority level of the warning message. This is an After variable and it returns an integer. ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.
