Optional objects

Optional objects

You can configure objects in a Visio template data flow as optional. When data is not passed to an optional object in a
mapping
task, the object is not included in the final data flow for the task.
You can configure any object as optional except source or source qualifier objects.
For example, you might have an optional Expression object that updates the date format of date data routed from the source. The updated data is routed back to the main data flow. If the source selected for the task does not include date data or a date field that is routed to the Expression object, I
Data Integration
omits the optional Expression object from the final data flow used for the task.
When you use an optional object, make sure the data flow is still valid if the object is not included. If the data flow is not valid without the optional object, errors can occur when the task runs.
To configure an object as optional, on the Properties page of the object details dialog box, set the
Optional
property to
True
.
