# Update a full routing input item for a quote part line item Unless enabled for the account, lines assigned to an operation are not supported: the operation keeps its own copy of the line's quantities, so a change to \`valueTypeUnits\` or \`fixedUnits\` is reverted when the routing is next loaded.
