how to determine which billing schedule recurrence should be processed for a certain sales order ?

AI generated answer (using internal Slack threads):

To determine which billing schedule recurrence should be processed for a certain sales order, you need to associate the billing schedule with the sales order. This can be done in the sales order form where you can select the billing schedule. The billing schedule recurrence is determined by the recurrence count and recurrence frequency. For example, if you want to bill 50% of the total amount in two installments, you would set the recurrence count to 2. NetSuite will then divide the total amount by the recurrence count to determine the amount for each billing. If you want to change the billing schedule on an existing sales order, you can export the sales order lines from a saved search and then import them with the correct billing schedule. Make sure the billing schedule exists before you do this. As for the billing dates on the invoice line item columns, they are copied from the sales order, not from the billing schedule. If you want to display the correct dates on an invoice, you might need to use a script. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
