求翻译：如果货物上有任何变更或修改使得工作量和所需装配的材料或设备减少，则订单额度也会相应减少，且因达不到预期利润导致供应商无法给予价格上打折。是什么意思？

If there are any changes or modifications made on the goods and Assembly of materials or equipment required to reduce workload, the order amount is also reduced, and falls short of the expected profit result in vendor not to give discounts on the price.
