ABAP程序并行处理

• CASE1. 程序中 start new task ,并在后面获取处理结果

• 20.1.2.             RFC函数：远程调用

  20.1.2.1.       同步

  CALL FUNCTION func [DESTINATION dest]  [?desti?nei??n]

  （在DESTINATION不省略的情况下，且dest取值又不为SPACE，则函数一定要是RFC函数才能采用此方式进行远程同步调用）

  20.1.2.2.       异步

  CALL FUNCTION rfm_name STARTING NEW TASK [DESTINATION dest]taskname PERFORMING return_form ON END OF TASK
  
  FORM return_form USING taskname.
    ...
    RECEIVE RESULTS FROM FUNCTION rfm_name
    ...
  ENDFORM.

  等待多个异步调用的返回结果：WAIT UNTIL log_exp [UP TO sec SECONDS].

  异步调用时不能有IMPORTING参数；函数一定要是RFC函数才能采用异步调用；只要有STARTING NEW TASK选项，即为异步调用；如果是异步调用同一目标端的RFC函数，则可以省略DESTINATION
