You can further customize the SCD processing logic by modifying these compon-
ents. Double-clicking the main Slowly Changing Dimension transform relaunches the
wizard. The wizard remembers your settings from the previous run; however, it will
overwrite any changes or customizations you've made to the existing transforms. This
includes any layout and resizing changes you might have performed.
Note When you re-run the Slowly Changing Dimension Wizard, the default options
selected in the UI are not inferred from the components. Instead, they are persisted as
part of the package in <designTime> elements. If you have a deployment process
that removes package layout information, note that you will also lose your choices in
the wizard.
