创建IDOC

第一步:WE31 创建IDOC所包含的字段.
第二步:WE30 创建IDOC 把Segment分配给IDOC
第三步:WE81 创建信息类型
第四步:WE82 把IDOC类型与信息类型对应.
第五步:WE57 Assign Message & Idoc Type to a Function Module for Data Process
第六步:SM59 Define a RFC connection for Idoc transfer
第七步：WE21 Define a Port ( Assign a RFC destination which created in SM59 )
第八步：WE41/42 Creat Process Code
第九步：WE20 Define a Partner Profiles( Also creat a Outbound parameters with Port, or Inbound

parameters with Process code )
管理IDOC:
WE02 显示IDOC,可以根据时间，IDOC类型查找IDOC，查看成功，出错信息。
WE46 IDOC管理(出\入)
WE60 IDOC类型文档(可以查看IDOC结构,和每个字段的描述.
WE19 根据IDOC号进行IDOC处理，可以修改IDOC值进行补发动作，处理分为内向和外向。
消息配置：
WE20 配置伙伴消息进和出IDOC类型
WE21 配置伙伴
