I'm attempting to perform an upload to set qty to 0 on a line. My upload contains: SO Internal ID, Line ID and Quantity I get this error: This update cannot be completed because the Line Id 3 is already used by a component of a kit/package or assembly item. To create a new line, leave the Line ID empty. The line is NOT used by a component of the kit, but there's an assembly on the order that also contains this item. Any idea how I can make this upload work? I can do it manually in the UI w/ no issue.
