生产模式的确定是有物料主数据MRP3视图中的策略组定义的。下面已策略组为源头，反向推理物料的生产模式
1、物料MRP3视图策略组
2、策略组SPRO定义：（Production/Production Planning/Demand Managent/Planned Independent Requirements/Planning Strategy/Define Strategy Group）
策略组可以分配一个主策略和其他策略
3、根据策略组可以找到策略：（Production/Production Planning/Demand Managent/Planned Independent Requirements/Planning Strategy/Define Strategy ）OPPS
参数解释：
Reqmts type for indep.reqmts：独立需求类型
Reqmt type of customer reqmt：客户需求类型
其他参数是由这需求类型带出来的。
4、独立需求类型定义与需求类的关系 Define requirements types and allocate requirements class：（Production/Production Planning/Demand Managent/Planned Independent Requirements/Requirements Types/Requirements Classes/Define requirements types and allocate requirements class ）OMP1
5、独立需求类定义：（Production/Production Planning/Demand Managent/Planned Independent Requirements/Requirements Types/Requirements Classes/Maintain requirements classes）OMPO
PI:Planning Indicator(计划标识)
- 1-Net requirements planning（MD02,MRP运算考虑库存）
- 2-Gross requirements planning（MD02,MRP运算不考虑库存，计划多少生产多少）
- 3-Individual requirements planning（MD02,MRP运算考虑库存，生产原材料采购需求和半成品生产需求，不产生产成品生产需求）
cons：Consumption indicator（消耗标识）控制客户需求如何消耗独立需求
This option has function if your planning will be consumed by sales order or not.
No consumption with customer requirements
1 Consume planning with assembly
2 Consume planning w/o assembly
3 Consume planning material (w/o assembly)2/3这两个选项不能理解，有谁知道的，麻烦留言。谢谢！
6、客户需求定义（sales and distribution/basic funcitons/availability check and transfer of requirements/rransfer of requirements/definrequirements classes）OVZG
Allocation Indicator
No consumption with customer requirements
1 Consume planning with assembly
2 Consume planning w/o assembly
3 Consume planning material (w/o assembly)这里的分配标识与前面的消耗标识又有什么区别呢？不能理解。
NO MRP
Requirement planned
1 Requirement not planned, but displayed
2 Requirements neither planned or displayed
