SAP求指导

[幽助]

我们部门的脚本和公司有一些数据通讯，使用SAP传输一些数据，但是有时候传输数据时会丢失，现在要去修改，不管是不是成功都要将数据发给财务，由于第一次接触SAP，所以对SAP一点都不了解，求高人指点，谢谢

public void RFCJAVAR3(String proj, String perso, String detail)
  {
    JCO.Client client = null;

    try {
      // Get a function template from the repository
      IFunctionTemplate ftemplate = repository.getFunctionTemplate("ZRFC_GET_PERSO");

      // if the function definition was found in backend system
      if(ftemplate != null) {

        // Create a function from the template
        JCO.Function function = ftemplate.getFunction();

        // Get a client from the pool
        client = JCO.getClient(SID);

        // Fill in input parameters
        JCO.ParameterList input = function.getImportParameterList();

//        input.setValue("0000000004", "ZINFO"   );
        //??????????  input.setValue("0000000003", "INPUT_SO"   );
        Structure dd =input.getStructure("INFO");
        dd.setValue(proj, "PROJ");
        dd.setValue(perso, "PERSO");
        dd.setValue(detail, "DETAIL");
        input.setValue(dd, "INFO"   );
        // Call the remote system
        client.execute(function);

        
        
        
        // Print return message
      //JCO.Structure ret = function.getExportParameterList().getStructure("WA_VBAK");
        JCO.ParameterList 	ret = function.getExportParameterList();
       
        System.out.println("-----------------------------------------");
        System.out.println("ZRFC_JAVA_LINK_R3 Done" );

      }
      else {
        System.out.println("ZRFC_JAVA_LINK_R3 not found in backend system.");
      }//if
    }
    catch (Exception ex) {
      System.out.println("Caught an exception: \n" + ex);
    }
    finally {
      // Release the client to the pool
      JCO.releaseClient(client);
    }
  }

传输的应该是这块代码吧，以前做写这个的同事都不在了，麻烦指点
