我刚刚开始编写 ABAP 代码几天，我的任务是从事务中调用报告SE38并有

报告的结果显示在 WebDynPro 应用程序的屏幕上SE80。

报表以用户输入（例如：物料编号、物料类型、工厂、销售组织）作为查询条件，因此 WebDynPro 应用程序必须允许用户键入此参数。

在一些相关文章中，他们正在谈论使用SUBMIT rep EXPORTING LIST TO MEMORY ，CALL FUNCTION 'LIST_FROM_MEMORY'但到目前为止我真的不知道要实现它。

任何答案将不胜感激。谢谢！

您可以将其导出为 PDF。因此，当用户单击链接时，您将运行转换并在浏览器窗口中显示文件。

为此，您首先使用以下代码创建一个 JOB：

  constants c_name type tbtcjob-jobname value 'YOUR_JOB_NAME'.

  data v_number type tbtcjob-jobcount.
  data v_print_parameters type pri_params.

  call function 'JOB_OPEN'
    exporting
      jobname          = c_name
    importing
      jobcount         = v_number
    exceptions
      cant_create_job  = 1
      invalid_job_data = 2
      jobname_missing  = 3
      others           = 4.

  if sy-subrc = 0.
    commit work and wait.
  else.
    EXIT. "// todo: err handling here
  endif.

然后，您需要获取打印机参数才能提交报告：

call function 'GET_PRINT_PARAMETERS'
  exporting
    destination            = 'LP01'
    immediately            = space
    new_list_id            = 'X'
    no_dialog              = 'X'
    user                   = sy-uname
  importing
    out_parameters         = v_print_parameters
  exceptions
    archive_info_not_found = 1
    invalid_print_params   = 2
    invalid_archive_params = 3
    others                 = 4.

v_print_parameters-linct = 55.
v_print_parameters-linsz = 1.
v_print_parameters-paart = 'LETTER'.

现在您使用适用的过滤器提交您的报告。不要忘记向其中添加作业参数，如下面的代码所示：

  submit your_report_name
         to sap-spool
         spool parameters v_print_parameters
         without spool dynpro
         with ...(insert all your filters here)
         via job c_name number v_number
         and return.

  if sy-subrc = 0.
    commit work and wait.
  else.
    EXIT. "// todo: err handling here
  endif.

之后，您关闭作业：

  call function 'JOB_CLOSE'
    exporting
      jobcount             = v_number
      jobname              = c_name
      strtimmed            = 'X'
    exceptions
      cant_start_immediate = 1
      invalid_startdate    = 2
      jobname_missing      = 3
      job_close_failed     = 4
      job_nosteps          = 5
      job_notex            = 6
      lock_failed          = 7
      others               = 8.

  if sy-subrc = 0.
    commit work and wait.
  else.
    EXIT. "// todo: err handling here
  endif.

现在工作将继续进行，您需要等待它完成。用循环来做。作业完成后，您可以获得它的假脱机输出并转换为 PDF。

  data v_rqident type tsp01-rqident.

  data v_job_head type tbtcjob.

  data t_job_steplist type tbtcstep occurs 0 with header line.

  data t_pdf like tline occurs 0 with header line.

  do 200 times.

    wait up to 1 seconds.

    call function 'BP_JOB_READ'
      exporting
        job_read_jobcount     = v_number
        job_read_jobname      = c_name
        job_read_opcode       = '20'
      importing
        job_read_jobhead      = v_job_head
      tables
        job_read_steplist     = t_job_steplist
      exceptions
        invalid_opcode        = 1
        job_doesnt_exist      = 2
        job_doesnt_have_steps = 3
        others                = 4.

    read table t_job_steplist index 1.

    if not t_job_steplist-listident is initial.
      v_rqident = t_job_steplist-listident.
      exit.
    else.
      clear v_job_head.
      clear t_job_steplist.
      clear t_job_steplist[].
    endif.

  enddo.

  check not v_rqident is initial.

  call function 'CONVERT_ABAPSPOOLJOB_2_PDF'
    exporting
      src_spoolid              = v_rqident
      dst_device               = 'LP01'
    tables
      pdf                      = t_pdf
    exceptions
      err_no_abap_spooljob     = 1
      err_no_spooljob          = 2
      err_no_permission        = 3
      err_conv_not_possible    = 4
      err_bad_destdevice       = 5
      user_cancelled           = 6
      err_spoolerror           = 7
      err_temseerror           = 8
      err_btcjob_open_failed   = 9
      err_btcjob_submit_failed = 10
      err_btcjob_close_failed  = 11
      others                   = 12.

如果您要通过 HTTP 发送它，您可能还需要将其转换为 BASE64。

  field-symbols <xchar> type x.
  data v_offset(10) type n.
  data v_char type c.
  data v_xchar(2) type x.
  data v_xstringdata_aux type xstring.
  data v_xstringdata type xstring.
  data v_base64data type string.
  data v_base64data_aux type string.

  loop at t_pdf.
    do 134 times.
      v_offset = sy-index - 1.
      v_char = t_pdf+v_offset(1).
      assign v_char to <xchar> casting type x.
      concatenate v_xstringdata_aux <xchar> into v_xstringdata_aux in byte mode.
    enddo.
    concatenate v_xstringdata v_xstringdata_aux into v_xstringdata in byte mode.
    clear v_xstringdata_aux.
  endloop.

  call function 'SCMS_BASE64_ENCODE_STR'
    exporting
      input  = v_xstringdata
    importing
      output = v_base64data.

  v_base64data_aux = v_base64data.

  while strlen( v_base64data_aux ) gt 255.
    clear t_base64data.
    t_base64data-data = v_base64data_aux.
    v_base64data_aux = v_base64data_aux+255.
    append t_base64data.
  endwhile.

  if not v_base64data_aux is initial.
    t_base64data-data = v_base64data_aux.
    append t_base64data.
  endif.

你完成了！

希望能帮助到你。

正如前面的演讲者所说，在生产环境中实施这些东西之前，您应该进行广泛的培训。
但是，在报表中调用 WebdynPro ABAP 可以借助WDY_EXECUTE_IN_PLACE功能模块来完成。您应该在那里传递 Webdyn Pro 应用程序和必要的参数。

CALL FUNCTION 'WDY_EXECUTE_IN_PLACE'
 EXPORTING
*   PROTOCOL                     =
    INTERNALMODE                 = ' '
*   SMARTCLIENT                  =
    APPLICATION                  = 'Z_MY_WEBDYNPRO'
*   CONTAINER_NAME               =
    PARAMETERS                   = lt_parameters
    SUPPRESS_OUTPUT              =
    TRY_TO_USE_SAPGUI_THEME      = ' '
 IMPORTING
    OUT_URL                       = ex_url
.

IF sy-subrc <> 0.
* Implement suitable error handling here
ENDIF.
