原生 SQL 程序和 ALV 布局

Question

我使用 from tCode = SE38 创建了一个程序 我正在使用本机 SQL。

这是我的代码：

DATA: BEGIN OF GetData OCCURS 0,
        AUFNR Type COAS-AUFNR,
        AUART     Type COAS-AUART,
        END OF GetData.

EXEC SQL PERFORMING loop_output.
SELECT AUFNR, AUART 
INTO STRUCTURE :GetData 
FROM Mytable
Where (MANDT = 450)
ENDEXEC.
FORM loop_output.

  WRITE: / GetData-AUFNR,
        GetData- AUART.
ENDFORM.

一切运行良好。

现在我想将此报表添加到 ALV 布局中，我该怎么做？

Answer 1

好的，首先我会将您的结构创建为一个类型，然后创建一个该类型的表以传递给 SALV。我在这个例子中使用了 SALV，因为它更容易。您需要一个表类型作为结构格式传递给 SALV，它目前无法通过您的声明识别。我删除了代码中的 mant where 子句，因为在我们的系统中，我们无法通过客户端查询。 perform设置alv设置，然后display方法执行。

TYPES: BEGIN OF ty_getdata,
         aufnr TYPE coas-aufnr,
         auart     TYPE coas-auart,
         END OF ty_getdata.

 DATA: lt_getdata type TABLE OF ty_getdata.

 DATA: gr_salv      TYPE REF TO cl_salv_table,
       gr_functions TYPE REF TO cl_salv_functions,
       gr_display   TYPE REF TO cl_salv_display_settings,
       gr_columns   TYPE REF TO cl_salv_columns.

 SELECT aufnr auart
   INTO CORRESPONDING FIELDS OF TABLE lt_getdata
 FROM mytable.

   PERFORM alvsettings.

   gr_salv->display( ).

*&---------------------------------------------------------------------*
*&      Form  alvsettings
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
*  -->  p1        text
*  <--  p2        text
*----------------------------------------------------------------------*
FORM alvsettings .

  cl_salv_table=>factory( IMPORTING r_salv_table = gr_salv
                          CHANGING t_table = lt_getdata ).

  gr_functions = gr_salv->get_functions( ).
  gr_functions->set_all( abap_true ).

  gr_display = gr_salv->get_display_settings( ).
  gr_display->set_striped_pattern( cl_salv_display_settings=>true ).
  gr_display->set_list_header( 'SALV Output' ).

  gr_columns = gr_salv->get_columns( ).
  gr_columns->set_optimize( 'X' ).

ENDFORM.                    " alvsettings

Answer 2

这里是一些 cmets 的示例。

一、数据定义

TYPE-POOLS slis. "import you need for REUSE_ALV_FIELDCATALOG_MERGE

DATA:
  lt_fieldcat TYPE slis_t_fieldcat_alv,

  BEGIN OF G_IT_MATERIAL occurs 0,
    MATNR LIKE MARA-MATNR,
    MTART LIKE MARA-MTART,
    MAKTX_DE LIKE MAKT-MAKTX,
    MAKTX_FR LIKE MAKT-MAKTX,
    MAKTX_IT LIKE MAKT-MAKTX,
    ERNAM LIKE MARA-ERNAM,
    ERSDA LIKE MARA-ERSDA,
    LAEDA LIKE MARA-LAEDA,
  END OF G_IT_MATERIAL.

绝对有必要直接用 LIKE 定义本地结构，否则 REUSE_ALV_FIELDCATALOG_MERGE 的解析器将找不到它。

选择你的东西：

 SELECT ma~matnr ma~mtart ma~ernam ma~ersda ma~laeda
 de~maktx as maktx_de fr~maktx as maktx_fr it~maktx as maktx_it
 FROM mara as ma
 LEFT JOIN MAKT as de ON de~matnr = ma~matnr AND de~spras = 'DE'
 LEFT JOIN MAKT as fr ON fr~matnr = ma~matnr AND fr~spras = 'FR'
 LEFT JOIN MAKT as it ON it~matnr = ma~matnr AND it~spras = 'IT'
 INTO CORRESPONDING FIELDS OF TABLE g_it_material
      WHERE ...

动态创建字段目录

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
I_PROGRAM_NAME        = sy-repid

I_INTERNAL_TABNAME    = 'G_IT_MATERIAL'

I_INCLNAME            = sy-repid
CHANGING
ct_fieldcat            = lt_fieldcat
EXCEPTIONS
inconsistent_interface = 1
program_error          = 2
OTHERS                 = 3.

IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

现在显示该 ALV 网格

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
it_fieldcat   = lt_fieldcat                 "you could also give a structure
"i_structure_name      = 'ZMM_SMATERIAL'    "here instead of the fieldcat
TABLES
t_outtab      = g_it_material
EXCEPTIONS
program_error = 1
OTHERS        = 2.

请注意，解析器还需要最大行大小为 72。
