Please specify a discount item for this customer error in invoice csv upload

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you are encountering an error when trying to specify a discount item for a customer in an invoice CSV upload. One possible solution could be to create a Discount item for the specific amount you want to discount. This can be done by setting up discounts as Service Items. This allows them to use billing schedules on this type of order. When creating the discount service item, you would use a quantity of 1 (or 12, depending on how you have things set up) and a negative $ amount for the discount. Another approach could be to create a custom record for the discount and attach it to the project record as a sublist. This custom record could contain multiple fields such as Employee, Discount Type (Percent/Flat), Discount Unit, Discount Description, Project (reference Link), Duration (From Date, To Date). When creating invoices, a User Event script could be deployed on the Invoice that adds a custom discount line item for every employee enabled for discount. The name of the item would be static, but the description could be customized dynamically via script. Remember to customize the Advance PDF template to incorporate these changes. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
