When integrating views an additional step is required if you want WhereScape RED to be able to recreate the view.
The view will be mapped correctly and the Get Key function can still be built. This step is only required if the view is to be re-created.
The Get Key function is not available for dimension objects that are stored in custom database targets.
Change the source column on the artificial key to match the artificial key in the table from which the view was created.
