How to execute a external command ?

carlos_zhang3 — Wed, 13 Jun 2007 08:11:03 GMT

Hi all ,

I would like to transfer the oracle data to sql2000 , my idea is :

- 1. write a external java program ( call trans.jar ) on oracle db server machine ( call sql2000 server to invoke the dtsrun.exe )

- 2. create a dts package on sql2000 server .

- 3. write an abap program in sap ( when the end-user execute this program , the trans.jar will call the dts package on sql2000 server ) .

I know that we can use sm69 to define the external program , but i don't know how to use abap/4 to invoke this external program ? has someone can tell me how to do ?

Thanks a lot !

Best Regards,

Carlos

You can use the function module <b>SXPG_COMMAND_EXECUTE</b> to execute external commands

Please find my sample code for it.


*&---------------------------------------------------------------------*
*&      Form  TRIGGER_EXT_OS_COMMAND
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
*      -->P_F_UNIX  text
*----------------------------------------------------------------------*
form TRIGGER_EXT_OS_COMMAND using P_F_UNIX type SXPGCOLIST-PARAMETERS.
  data: begin of IEPCOL occurs 100.
          include structure BTCXPM.
  data: end of IEPCOL.
 BTCXPM = Log message from external program to calling program

  data: W_STATUS like EXTCMDEXEX-STATUS.
* EXTCMDEXEX = Parameters of SXPG_COMMAND_EXECUTE

  data: W_HOST like RFCDISPLAY-RFCHOST.
* RFCDISPLAY = Display structure for RFCDES maintenance          "M5

* The External operating system command ZECOM is created * using thetransaction SM69. For any changes to the 
* command goto SM69 and for executing and testing use 
* the transaction SM49.

  W_HOST = SY-HOST.

  call function 'SXPG_COMMAND_EXECUTE'
    exporting
      COMMANDNAME                   = 'ZECOM'
      ADDITIONAL_PARAMETERS         = P_F_UNIX
      OPERATINGSYSTEM               = SY-OPSYS

      STDERR                        = 'X'
      TERMINATIONWAIT               = 'X'
    importing
      STATUS                        = W_STATUS
