1.前台操作

SAP CO01(创建生产订单)/MIGO(发货投料)前台操作
这里面有migo的前台操作,首先了解前台操作后再去写RFC接口是比较容易理解的.!!

2.需求分析

2.1调用方式

mesOS->SAPOS

2.2分为两大概括:

同一过账标识 1 和 0

1. 为 0 的时候单一过账,无论行项目中有多少个物料号,都会对应生成多少个物料凭证号
2. 为 1的时候同一过账,也就是无论行项目中有多少个物料号,都只生成一个物料凭证编号.
   这两个逻辑是是相反的.

2.3业务逻辑细节图

3.BAPI_GOODSMVT_CREATE

下面的这些参数我只介绍了此需求用过的.

EXPORTING部分
bapi2017_gm_head_01,   "凭证中的过帐日期等一些抬头信息
bapi2017_gm_code,        "这个是你要进行的是什么样的操作比如说是发货,收货,取消等都对应相应的编号比如01 02 03

IMPORTING部分
bapi2017_gm_head_ret,  "物料凭证号,凭证年度
bapi2017_gm_head_ret-mat_doc, "物料凭证号
bapi2017_gm_head_ret-doc_year, "凭证年度

TABLES部分
 bapi2017_gm_item_create, "行项目
 bapiret2, "返回值

4.RFC接口代码

代码感觉比较臃肿,欢迎大佬前来补充优化!!!

5.总结

RFC接口首先要明确的是,接口参数以及业务逻辑.(我尼玛,说的都是废话);如果调用bapi就需要研究一下bapi中的参数.
