why do i have to add the location in the lines of sales order even though i added it to the header

AI generated answer (using internal Slack threads):

In NetSuite, the location field at the line level of a sales order is independent of the location field at the header level. This is because each line item in a sales order can potentially be fulfilled from a different location. Therefore, even if you have set a location at the header level, you still need to specify the location for each line item. This design allows for greater flexibility in managing inventory across multiple locations. For example, if you have a sales order with multiple items, and these items are stored in different locations, you can specify these locations at the line level. This way, when the sales order is fulfilled, the correct quantities of each item can be deducted from the appropriate locations. If you want the location at the line level to automatically populate from the location at the header level, you would need to create a workflow or a script. However, please note that this might not always be the best approach, as it could limit the flexibility of managing inventory across multiple locations. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
