can not add a new line to a partially fulfilled sales order without getting this error The Location cannot be changed because inventory has already been fulfilled against the line

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that once a Sales Order has been partially fulfilled, you cannot change the location on the line item. This is because the Sales Order represents a commitment with no real GL Impact (in Pending Fulfillment Status), and the Fulfillment consumes the inventory which is sitting in a Location (the one coming from the Sales Order line) at creation time. NetSuite does not allow you to change the location of a line that is already fulfilled for several reasons: - The new location may not have enough inventory available. - Locations in NetSuite behave as costing centers under the hood, accounting-wise. If you need to fulfill from a different location, you would need to create a new line in the Sales Order and commit from the new location. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
