可以通过函数 CP_EX_PLAN_READ对PP模块中的routing进行展开。
SE37，展开的结果放在各个Table参数中。
前台可以通过tcode：CA03来查看routing的展开
输入物料，工厂，销售订单和行项目后回车，
下面这个例子将2中的工厂 8800，物料SMA50620100，销售订单690000090行项目100的对应的routing展开。
简单逻辑：
1，从MAPL中取得routing对应的group和group counter
2，调用函数CP_EX_PLAN_READ展开
其中，
task list type：
status：04是release
Task list usage:

运行代码，加断点debug测试，可以发现展开的结果保存在函数返回内表中。
以组件分配(Allocation)为例，组件分配保存在内表git_plmz_exp中，
在CA03中也可以看到组件分配情况，与内表中内容一致。
以上。
