1.BAPI种类

1. BAPI_SALESORDER_CREATEFROMDAT2
2. BAPI_CUSTOMERRETURN_CREATE
3. SD_SALESDOCUMENT_CREATE

2.BAPI区别

• BAPI_SALESORDER_CREATEFROMDAT2 业务对象限制为BUS2032
• BAPI_CUSTOMERRETURN_CREATE 业务对象限制为BUS2102
• SD_SALESDOCUMENT_CREATE 未限制业务对象类型
  • BUS2030 客户询价单
  • BUS2031 客户报价
  • BUS2032 销售订单
  • BUS2034 合同
  • BUS2094 贷项订单
  • BUS2096 借项订单
  • BUS2102 退货订单
  • BUS2103 后续免费送货订单
• BAPI_SALESORDER_CREATEFROMDAT2和BAPI_CUSTOMERRETURN_CREATE都在内部调用SD_SALESDOCUMENT_CREATE
• 对于不同订单类型（Z001，Z002…），配置了的SD凭证类型；可在TVAK表中VBTYP字段查看
  
  
• 业务对象和SD凭证类型有绑定关系；比如Z008 Z009凭证，SD凭证类型为H（退货）所以需要使用业务对象类型BUS2102的BAPI；或者使用SD_SALESDOCUMENT_CREATE并设置参数BUSINESS_OBJECT = ‘BUS2102’

3.创建抬头行项目输入结构

4.创建接口函数，并配置传入传出参数

5.代码

• 此方法save_text切割的字符串结尾为空格时；会造成空格丢失，需要自行写逻辑处理
• 处理逻辑：缩短切割长度（例如：120）；然后判断前一行是否末尾为空格，如果空则将空格写入本行开头
