Removing a Catalog
To remove a catalog, including its categories and its categories’ products, from both the Siebel application and ATG Web Commerce, set the effective end date of the catalog, and then create a Web content export job to export the change to ATG Web Commerce.
Physically deleting a Catalog record, Category record or Category Product record is also supported, but it is not recommended because it becomes impossible to trace which objects have been removed.
To remove a catalog
Navigate to the Administration - Catalog screen, then the Catalog view.
In the record for the catalog that you want, enter a value in the Effective End Date field that is before the current date.
This field is in the Administration - Catalog applets:
Catalog Admin Catalog List Applet
Catalog Admin Catalog Detail Applet
Click Update Commerce App.
