from the PReS Workflow Configuration Tool, in order to detect and resolve issues with your
process.
Error Handling, on the other hand, occurs when your configuration has been sent to PReS
Workflow services, and are running in "production"mode. On one hand the manual task is
critical when creating a process, on the other the automated handling of errors within your
processes will have a large impact on recovering from errors as they happen during production.
About Error Handling
When your process is running, or during debugging, it may happen that the task that is currently
running causes an error, and the task fails. For example, when trying to save to a folder that
does not exist, or printing to a printer that cannot be found.
When such an error occurs, in most cases you would want to be aware of it and to take certain
actions in order to correct or report the error. This is where our error handling features come in
handy.
Most of the tasks, branches and conditions included in your process can have their own error
handling behavior, with the exception of Comments, the Input Error bin task, and older legacy
tasks from previous versions of PReS Workflow that did not have error handling.
By default, when an error occurs, the task is skipped and the unmodified job file is passed on to
the next task. You can overwrite this behavior by changing the options of the On Error tab of
the task.
Using the On Error tab
Whenever an error is triggered either during debugging or when a process runs in production,
the settings specified in the On Error tab of the task that generated the error will be used to
determine a course of action.
On Error Tab
The On Error Tab is common to all tasks. Details can be found on " Task Properties Dialog" on
page 584.
By default, any action task, branch, splitter or condition that generates an error will simply be
ignored, and the task just under it (not within a branch)will be given control of the job file
