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.

The component in this framework is available in all Talend
products.

Basic settings

Warn message	Type in your warning message.
Code	Define the code level.
Priority	Enter the priority level as an integer.

Global Variables

Global Variables	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. To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it. For further information about variables, see Talend Studio User Guide.
