"You can not over-fulfill an item unless you have selected the 'Allow Overage on Item Fulfillments' preference."

AI generated answer (using internal Slack threads):

In NetSuite, there is a setting that allows over-fulfillment of items. This setting is called 'Allow Overage on Item Fulfillments' and it is located under accounting preferences. When this preference is enabled, it allows users to fulfill more quantity than what is specified in the Sales Order or VRA. However, it's important to note that enabling this preference might have accounting implications that you might not desire. Therefore, it's recommended to understand the implications before enabling this setting. If you find that over-fulfillment is still happening even when this preference is unchecked, it could be due to a script or workflow that is overriding this setting. In such cases, you would need to identify and modify the script or workflow to prevent over-fulfillment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
