Webdynpro调用期间的COMMUNICATION_FAILURE？

Question

我已经创建了一个简单的WebDynpro应用程序，它调用了一个BAPI。但是，我得到一个错误，因为RFC不是设置。

如何设置RFC调用？

错误：call调用由于一个错误而终止。

The following error text was processed in system EH5 : RFC Exception COMMUNICATION_FAILURE with Message RFC destination BAPI Call does not exist. Occurred 
◾ The error occurred on the application server CRMEHP2_EH5_24 and in the work process 0 . 
◾ The termination type was: RABAX_STATE
◾ The ABAP call stack was: 
Method: EXECUTE_BAPI_FLIGHT_GETLIST of program /1BCWDY/0AA4D2ZOSMWRNSH8KCQZ==CP
Method: IF_COMPONENTCONTROLLER~EXECUTE_BAPI_FLIGHT_GETLIST of program /1BCWDY/0AA4D2ZOSMWRNSH8KCQZ==CP
Method: WDDOINIT of program /1BCWDY/0AA4D2ZOSMWRNSH8KCQZ==CP

Method: INIT of program CL_WDR_CONTROLLER=============CP
Method: GET_VIEW of program CL_WDR_VIEW_MANAGER===========CP
Method: BIND_ROOT of program CL_WDR_VIEW_MANAGER===========CP

在webdynpro WDDOINIT方法中调用过程bapi_flight_getlist：

method WDDOINIT .
  DATA lo_componentcontroller TYPE REF TO ig_componentcontroller .
  lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).

    lo_componentcontroller->execute_bapi_flight_getlist(
     airline =    'AA'                       " bapisflkey-airlineid
*     destination_from =                  " bapisfldst
*     destination_to =                    " bapisfldst
*     max_rows =                          " bapisflaux-bapimaxrow
    ).

endmethod.

execute_bapi_flight_getlist定义：

  CALL FUNCTION 'BAPI_FLIGHT_GETLIST'
    DESTINATION  'BAPI Call'
    EXPORTING
       airline =                         airline
       destination_from =                destination_from
       destination_to =                  destination_to
       max_rows =                        max_rows
    TABLES
       date_range =                      lt_c_date_range
       extension_in =                    lt_c_extension_in
       flight_list =                     lt_c_flight_list
       extension_out =                   lt_c_extension_out
       return =                          lt_c_return
    EXCEPTIONS
      system_failure =                    1   MESSAGE    lv_rfc_error
      communication_failure =             2   MESSAGE    lv_rfc_error.

我检查了sm59和一个BAPI调用RFC不存在。然而，还有其他RFC连接可以工作。

Answer 1

假设您不想调用远程系统：

变化

DESTINATION  'BAPI Call'

至

DESTINATION  'NONE'

如果它是一个远程系统，那么在SM59中创建一个目的地(但是没有空格)，然后引用它。
