Minimum & Maximum Price of Item

Dear All,

I would like to set the Minimum & Maximum price for the Sales items.

Example:- if i create a ONE item, i need to set the minimum price Rs.5 and Maximum Price Rs.8 so when a sales invoice made for this item, no one can sale this item with less then 5 and not more then 8 rs.

Please let me know if this is possible in ERP.
