MB_DOCUMENT_BADI调试(Update Debug)

Update Module函数,主要用语对话或报表中实现同步和异步更新数据库操作,需要单独调用函数实现更新数据库表,但又要求对程序的运行不产生影响(更新成功与否不影响主程序的正常执行)
几个操作,要么全部执行,要么全部不执行

执行顺序如下

  1. IF_EX_MB_DOCUMENT_BADI~MB_DOCUMENT_BEFORE_UPDATE
  2. POST_DOCUMENT(产生会计凭证)
  3. IF_EX_MB_DOCUMENT_BADI~MB_DOCUMENT_UPDATE

Method would get triggered in Update debugging mode. After setting the update debugging it would work . update debugging is setting values at runtime ....and checking values.

Update task是用于对话或报表中实现同步和异步更新数据库的功能,在Update之前还有一个Before Update,用于更新数据前的检查,当二者都执行完,才会进行到后面的commit,当before update成功执行,而update不成功,会报错如下,显示数据回滚: Express document "Update was terminated" received from author "xxx"

SAP is detecting that and rolling back the body of work that was just committed to the database.

T-code:SM13 and ST22 to analyse it

调试Update Task方法

  1. 在MB_DOCUMENT_BEFORE_UPDATE打上内部断点;
  2. 在MB_DOCUMENT_ UPDATE打上外部断点
  3. 在MB_DOCUMENT_BEFORE_UPDATE调试界面
    Settings-Display/Change Debugger Settings-Update Debugging

FM加入到update task的方式是:Call Function xxx in update task
