What is PO# while creating sales order?

AI generated answer (using internal Slack threads):

The PO# (Purchase Order Number) in the context of creating a Sales Order in NetSuite is typically used to reference the customer's purchase order number. This is often captured in the 'otherrefnum' field. It's a free-form field that can be included at the customer's request. In some cases, businesses may have multi-year orders where the customer provides a new PO# for each year. This PO# is typically captured on the invoice and sometimes on the Sales Order as well. However, changing the PO# on an approved Sales Order or Invoice can lead to compliance issues and is generally not recommended. If you need to handle changes to the PO# without modifying the approved Sales Order or Invoice, one possible solution could be to use a custom record or a similar source that can be updated with the new yearly PO reference. This way, the original Sales Order doesn't need to be changed after approval. Please note that this approach may require additional setup and customization in NetSuite, and it's always a good idea to consult with your finance team or a NetSuite professional to ensure compliance with your business processes and regulations. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
