BTE1650 FBL1N/FBL2N/FBL3N/FBL5N-增加客制化字段 客商及科目描述

TCODE:FIBF/BF24/BF34

查找BTE事件：FIBF->环境->信息系统

在清单中找到我们需要BTE事件，可以点击文件按钮查询事件的详细描述，点击模式函数模块找到具体的函数-SAMPLE_INTERFACE_00001650

复制标准函数到自定义函数组

实施BTE
BF24 或FIBF->设置->产品

BF34 或FIBF->设置->发布/订阅模块

3 APP-ALV显示结构(RFPOS&RFPOSX)

4、根据需求，对BTE事件对应的方法进行编码，填充对应的字段

function zsample_interface_00001650.
*"--------------------------------------------------------------------
*"*"局部接口：
*"  IMPORTING

*-------------- Initialize Output by using the following line ----------

  e_postab = i_postab.

  select single lifnr kunnr
          into (e_postab-lifnr,e_postab-kunnr)

          where belnr = e_postab-belnr
          and bukrs   = e_postab-bukrs

   where ktopl = '1000' 
     and saknr = e_postab-hkont 
     and spras = sy-langu.

endfunction.
