Common Errors
Though some error messages are specific to a task in particular, others may apply to any and
all tasks because they are related more to the system than to PReS itself. Some examples
would be W3813, W3830, W3991, W4005. These correspond to issues such as not having any
space to write files, permission errors on folders or files, etc.
Comments Tab
The Comments tab is common to all tasks. It contains a text area (Task comments)that lets
you write comments about the task. These comments are saved when the dialog is closed with
the OKbutton, and are displayed in the Task Comments Pane.
Check the option Use as step description to display the text next to the icon of the plugin in
the Process area.
Process Logic Tasks
A process is like a flowchart. The data files captured by the input tasks become job files (see
"Data File and Job File" on page23) that travel down the process. Many processes include
multiple process logic tasks.
In the Process area, conditional branches appear with their associated condition, allowing you
to understand the logic of the whole process at a glance. When PReS Workflow comes to a
condition, it tests the condition and sends the job file down one of the two branches based on
the test result. So every time a job file travels down the process, it is either routed down the
True or False branch.
Note
Branches, Loops and other process logic tasks do not generally modify the job file,
though some may change system variables. The only exception is the Run Script action,
which can be a condition that also modifies the data.
Warning
Branches, loops and conditions do NOTmodify metadata in any way. Furthermore, even
