Dynamic settings

Click the [+] button to add a row

field with a context variable to choose your pipe connection
dynamically from multiple connections planned in your Job.

When a dynamic parameter is defined, the Pipe box in the Basic
settings
view becomes unusable.

variables, see Talend Studio User Guide.

Global Variables

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.
