AI generated answer (using internal Slack threads):

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** The error message "You must enter at least one line item for this transaction" typically occurs when NetSuite is unable to find a bill to pay in the exact amount of the payment you are uploading. If there is even one incorrect line in a payment CSV file with multiple lines, the entire file will fail to upload. In the case of multi-currency vendors, the error can occur when the bill currency is different from the subsidiary currency. When creating bill payments automatically, you need to set the currency first before proceeding with the transaction. If the currency is not set, the bill payment currency defaults to the subsidiary's currency, which can cause the error if the bill is in a different currency. Additionally, make sure that all mandatory fields in the line item are included. If these fields are not included, you may encounter the error message. You can either untick the 'validate mandatory cost on fields' option or select a form where these fields are not mandatory. Lastly, ensure that you are running the import as an 'update' and not 'Add or update'. This can also help prevent the error from occurring.
