在以后月份付款时，除非发生的成本差异恰好与该项成本差异余额相抵销，一般也不能避免材料无余额而材料成本差异有余额的不合理现象。在实际工作中，一般不按材料品种计算材料成本差异率，而按材料类别计算材料成本差异率，因此，不论技哪一种组成内容计算，一般都不会由于个 In the future months of payment, unless the cost difference happens to offset the balance of the cost difference, it is generally not possible to avoid the unreasonable phenomenon that the material has no balance and the material cost difference has a balance. In actual work, material material cost difference rate is not generally calculated according to material types, but materials material cost difference rate is calculated according to material types. Therefore, no matter what kind of material composition is calculated, generally,
