how to add discount on base price item price leve

AI generated answer (using internal Slack threads):

To add a discount on the base price at the item price level, you can use a Flat Rate Discount Item. This item should be placed under the line that needs discounting. However, if you want to apply different percentage discounts on different line items on the Sales Order (SO), you can use a Discount Item. But by default, when you create a discount item, the discount is applied after sales tax has been calculated and applied to the items. If you want to calculate tax on total after discounts are made, you can refer to the NetSuite help document on 'Applying Sales Tax or VAT to Discount Items'. If you want to stop the price levels from being applied on a few specific items, you can create a custom checkbox for 'special pricing'. This way, you can identify the 'special pricing' items that you need to import all lines for. The only other way to do special pricing is by setting specific pricing per customer on the customer record, but that would be for each customer. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
