Mass deletion of price condition records

Sap Question from Tehseen Akbar

Is there a way to mass delete the price condition records.
I want to delete all the records maintained by VK11.

Best practice is to keep the old data - your auditors will probably agree with this.
If your users misuse the system a simple report of order creation date (VBAK) and pricing date (VBKD) will be able to determine which employees aren't working for the best of the business.
