需求：SAP在没有采用批次的情况下，取寄售库龄信息
前提条件：遵循先进先出逻辑
报表效果如下图：
程序设计：
1、 定义后台作业，每天从供应商特殊库存表mkol中取数据，并保存到表ztmm_mkol表中，
因为，物料在期间内没有货物移动的情况下，供应商特殊库存历史表mkolh是不更新的，
为了保证能取到历史期间的库存历史，所以定义后台作业并保存数据到ztmm_mkol
2、 查询ztmm_mkol
3、 查询mkpf,mseg里101移动类型的数据，并根据凭证过账日期，计算出每条物料凭证所属的库龄
4、 Mseg得出的库龄数据小于等于ztmm_mkol里的历史库存时，将mseg数量作为第N个月的库龄库存，否则，将ztmm_mkol里的历史库存作为第N个月的库龄库存
