但当选择“销售单位不可变” 时则所有的销售组织只能使用同一单位。-----这句话有出处吗？我看SAP官方help写的是：You can maintain the sales unit for each material and sales organization/distribution channel. The sales unit is proposed in Sales and Distribution (SD) documents such as sales orders. If a variable sales unit is not allowed, the unit specified in documents may not differ from that in the master record.-------也即，是用来控制物料主数据中的销售单位做为缺省值携带到销售凭证上后，是否允许手工再修改之（和物料主数据上的销售单位不一样了）。
