Provide the "Prevent entry of Special Prices below Base Cost or Minimum Sell" password option which will block the entry of a Customer Special Price which is below either Base Cost or Minimum Sell Price, whichever is lower.

 

This restriction is only applied to the edit grid on the "Special Pricing" tab of Inventory and Customer File Maintenance. Special Price, Bid Price 1 and Bid Price 2 are all restricted when this option is active.
