how to make items not required on a vendor bill?

AI generated answer (using internal Slack threads):

To make items not required on a vendor bill, you can leverage the 'Bill in Advance of Receipt' setting in NetSuite. If this setting is enabled, you can create a Vendor Bill against a Purchase Order without requiring an Item Receipt. This means you can bill for items that have not yet been received. However, please note that this setting might not be suitable for all business scenarios. For example, if you need to ensure that you only bill for items that have actually been received, you would need to disable this setting and use Item Receipts to control the billing process. For non-inventory items, you can also set the 'Can be fulfilled' field to 'False'. This allows you to go from an Approved Purchase Order to a Vendor Bill without requiring an Item Receipt. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
