Hello @kevinheng21 ,

Please, show us a screen shot of where the pricing is set, and where you see the price go wrong. We need to know if your system has customizations published on the sales price worksheets and/or on the screen where the price goes wrong. Thank you.

No customize on sale price worksheet. Set price here 

When we input sale order of this customer, it trigger the wrong price. After I restart IIS, It’s working propery
