maximum number of lines on an invoice

AI generated answer (using internal Slack threads):

The maximum number of lines allowed on an invoice in NetSuite varies depending on the method of input. If you are entering the data through the user interface, the limit is 500 lines. However, if you are submitting the data through CSV import or SOAP web services, the limit increases to 5,000 lines per transaction. After you submit transactions exceeding the 500 lines limit through the CSV import or SOAP web services, you must do all additional changes and edits through the CSV import or SOAP web services. For journal entries, these limits are 1,000 lines for the user interface and for synchronous SOAP web services, and 10,000 lines for CSV import and asynchronous SOAP web services. It's important to note that performance in the UI can be significantly impacted for any document at or near the line limits. If you need to create invoices with more than 20,000 lines, you might consider creating multiple invoices and using invoice grouping, or creating a custom child record that holds the detail of all 20,000 lines and do a few consolidated items/lines on the invoice. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
