I have many sales orders with multiple lines (1000+). I've added a field qty_stacked. I want to update the field. Right now, I have to open the SO, "move" to the line, update qty_stacked and save. As expected the save take a long time. Is there's a trick to update the lines directly ?

can't via xedit *(inline edit) or

record.submitFields

. AFAIK the only ways would be a script loading and saving the record or a csv import

It's 1,000 lines. A lot to chug through. Just FYI, NetSuite does have line limit recommendations.

maybe share your code to provide full context?
