Removing a Price List
To remove a price list, including its line items, from both the Siebel application and ATG Web Commerce, set the effective end date of the price list, and then create a Web content export job to export the change to ATG Web Commerce.
Physically deleting a price list and price list line item record is also supported, but it is not recommended because it becomes impossible to trace which objects have been removed.
To remove a price list
Navigate to the Administration - Pricing screen, then the Price Lists view.
In the record for the price list that you want, enter a value in the Effective To field that is before the current date.
