When products on a Purchase Order are receipted into stock, (Packing Slip or Supplier Invoice) and the Cost Price has changed, users get a prompt, "The cost price has changed. Do you want to update the selling prices?"
This is a system designed prompt and will show for all products that are set for Manual Pricing, those set up for Product Group Markup will not receive the prompt. To learn about the difference between the pricing methods see Product Pricing Methods.
If the selling price has been changed, the Rate will appear in Orange.
