Issue: Discount application changes payment method to "Payment Not Required" when discount pays the whole total of the order

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that the issue of the discount application changing the payment method to "Payment Not Required" when the discount pays the whole total of the order is not directly addressed. However, there are some related discussions about how discounts are applied in NetSuite. In the first conversation, the user is having an issue with the tax code not being set correctly when applying a discount to all items from the discount field. The user mentions that the discount is being applied to different boxes in the TAX-report. Another user suggests a workaround of not using the discount field on top of item lines, but instead adding a subtotal line item and then a discount line item, which allows for changing the tax code next to the discount line. In the second conversation, a user is trying to understand how the "Apply Before Sales Tax" option works for a discount item. They initially think that the total is calculated with tax first, then the discount is subtracted. However, they later realize that they were using a box that was applying the discount incorrectly and that the new Discount item has to be applied as a line item for it to calculate correctly. In the third conversation, a user is asking how to apply a 2% discount to all customer invoices if they pay within 20 days. The solution suggested is to assign a payment term with a 2% prompt payment discount setup. However, the user notes that this is impacting vendor payments too. The solution to this is to create unique terms for the vendor and 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. ******
