This message is normally displayed when no valid Price List has been found for the (price_list_no / contract / catalog_no / customer_no / currency_code / effectivity_date / sales_price_type / buy_qty_due / min_duration) combination of a Sales Quotation Line or a Customer Order Line.
@ChristianJ , We do have a valid price list linked to the customer and the part , Can you please advise how can i solve this error and should i look into.
Not sure why your price list is not considered as valid.
Maybe you could check again that the "Price List No" from your Customer Order Line corresponds to a valid Sales Price List: - does this Sales Price List exist for the right company / currency / sales price group - is this Sales Price List valid for the Site of the Customer Order - is the Part No present in this Sales Price List, and with a "Min Qty" <= CO Line "Sales Qty" and with valid From/To dates
You could also create a Price Query for the same Customer No/Contract/Currency/Part No/Qty as your Customer Order Line to see if the Price List is applied.
