how to the amount of the 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 seems that you are trying to change the location of a partially fulfilled sales order line in NetSuite. However, NetSuite does not allow you to change the location of a line that is already fulfilled or partially fulfilled. This is because the Sales Order represents a commitment/promise with no real GL Impact(In Pending Fulfillment Status), the Fulfillment consumes the inventory which is sitting in a Location(the one coming from the Sales Order line) at creation time. 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. This is because each fulfillment can only be from a single location. Here are the steps you can follow: 1. Delete the existing Item Fulfillment (IF) for the line you want to change. 2. Update the Sales Order (SO) by adding a new line for the item you want to fulfill from a different location. Set the location to the new location. 3. Create a new Item Fulfillment for the new line. Please note that this approach might not be suitable for all use cases. For example, if you have a large Sales Order that you fulfill over a long period of time, you might end up with many lines for the same item. In such cases, you might want to consider using SuiteScript to automate the process of splitting lines. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
