最近有个业务需要，MRP运行过程中需要根据生产计划订单/子件/供应商对应关系来拆解采购申请。
1.具体实例：
a.基础数据
整车物料：NL1G58420151001219
子件：000000008888002653
供应商：0000563007 / 0008000005
配额：
订单BOM:
b.创建计划独立需求T-CODE：MD61
c.MRP运行T-CODE：MD41
d.库存/需求清单T-CODE：MD04
综上：MRP运行后子件8888002653生成的采购申请是根据配额来分配供应商的。
新需求：生产某些车型需要的子件需要特定的供应商专供，针对该子件的其他采购需求还是按照配额来分配供应商。
该需求很无语，通过SPRO配置已无解，只能通过查找增强出口解决该问题了。
2.解决方式：
2.1自定义表
2.2增强点
在程序 LM61YF0J 行70 创建隐式增强点 ZIMP_BADI_MRP_VENDOR ，并插入 include zmmi0001_mrp_vendor.
2.4 INCLUDE ZMMI0001_MRP_VENDOR程序代码
