I was able to place a sales order for an inventory item one day, but now I no longer can. What could have changed that it would start returning an "Invalid Field Value" error?

AI generated answer (using internal Slack threads):

The "Invalid Field Value" error you're encountering when trying to place a sales order for an inventory item could be due to several reasons: 1. Inventory Status: The inventory status you're trying to set might not be a valid select option for the item. Ensure that the inventory status you're setting is valid for the item in question. 2. Inventory Detail: If you're trying to assign inventory details to a line when using inventory status, there might be an issue. There have been instances where this was not scriptable or there was a bug in NetSuite. 3. Issue Inventory Number: If you're trying to transform a Sales Order into an Invoice while populating the inventory details from the Item Fulfillment, you might encounter this error. This could be because NetSuite does not support direct transformation from Item Fulfillment to Invoice. You might be trying to replace the inventory detail which has already been issued, which could confuse NetSuite. 4. Line Item Validity: The error could also be due to the absence of at least one valid line item for the transaction. When creating an Item Fulfillment from a Sales Order, ensure that there is at least one valid line item. To troubleshoot, you could try creating the fulfillment in the UI first, inspect which fields are set with which values, and then recreate it in script. This could help you identify any discrepancies or missing fields in your 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. ******
