Error events are handled through the Event
handler. Each task and container may have a dedicated ON-ERROR event defined
for it. When an error occurs, the event handler is immediately
invoked for the event defined at the failing task level. ON-ERROR
events defined within a data flow (red line to a defined task) may be
configured to not fail the load and execute any defined tasks prior to going to
the next row. If no error-handling event is defined within a data
flow or the error occurs in the processes flow, control is transferred to the
next highest level of the package (ie. The container level). If an
ON-ERROR event is defined there, that code is executed, then control is raised
up the chain until the package ON-EVENT is reached. Once control
leaves a data flow for an ON-ERROR event, the package will not return to the
data flow.
