You always could fix the price and other information in Quotation. But if this line is extra information and you don't want to use it, you can disable this line.

  1. Start Buymanager
  2. Click on “Deal” Choose the deal you are working on
  3. Open "Quotation"
  4. Go to the wrong line choose the "Price status" and press" ▼"
  5. Choose "Declined/Not Quote"

This price won't use it in your costing and won't be showing in your part price as well.
