有多种使用 ALV 的方法,因此我们可能确实需要有关您的代码的更多信息来提供帮助。
- 第一种方法是使用功能模块REUSE_ALV_GRID_DISPLAY。这将直接在输出 dynpro 中显示表格内容。如果你只需要一个显示,那就去做吧,因为这是最简单的:如果表结构在字典中,这个调用可以像下面这样简单(这会将结构的所有成员显示为列)
myreport = sy-repid.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
i_callback_program = myreport
it_excluding = exclude_tab
TABLES
t_outtab = display_data
EXCEPTIONS
program_error = 1
OTHERS = 2.
如果在程序中声明了结构,那么您必须创建一个字段目录。以下代码可以作为基础:
FORM fill_fieldcat CHANGING p_fieldcat TYPE slis_t_fieldcat_alv.
* Data definition
DATA ls_fieldcat TYPE slis_fieldcat_alv.
* Macro definition
DEFINE append_fieldcat.
clear ls_fieldcat.
ls_fieldcat-fieldname = &1. * name of the field in struct
ls_fieldcat-tabname = &2. * name of the table
ls_fieldcat-row_pos = &3. * column
ls_fieldcat-ref_fieldname = &4. * field in ref table
ls_fieldcat-ref_tabname = &5. * ref table
ls_fieldcat-outputlen = &6. * size of output
ls_fieldcat-seltext_m = &7. * text (space if using the element typetext)
ls_fieldcat-ddictxt = 'M'.
ls_fieldcat-key = &8. * is this a key field in table
ls_fieldcat-emphasize = &9. * emphisze column display
append ls_fieldcat to p_fieldcat.
END-OF-DEFINITION.
* Init.
REFRESH p_fieldcat.
* Append fielcatalog for ALV
append_fieldcat:
'FORMATIONCODE' 'DISPLAY_TAB' 1 'SHORT' 'HRP1000' 12 'Code Stage' space space,
'FORMATIONTEXT' 'DISPLAY_TAB' 1 'STEXT' 'HRP1000' 20 'Libelle Stage' space space,
'SESSIONID' 'DISPLAY_TAB' 1 'OBJID' 'HRP1000' space 'Session' space space,
'BEGDA' 'DISPLAY_TAB' 1 'BEGDA' 'HRP1000' space 'Debut' space space,
'ENDDA' 'DISPLAY_TAB' 1 'BEGDA' 'HRP1000' space 'Fin' space space,
ENDFORM. "fill_fieldCat
然后调用表单来创建字段目录,并在函数调用的 it_fieldcat 参数中使用它。
- 第二种方法是使用 ABAP-Object。使用 check se83 作为此用途的示例。依据如下:
在您的 Dynpro 中,您声明一个具有给定名称(“ALV_CONT”)的自定义容器。然后在 dynpro 的 PBO 中初始化容器并在其中放置一个 ALV 对象:
* global variables :
DATA : delegationlist_table TYPE REF TO cl_gui_alv_grid,
delegationlist_container TYPE REF TO cl_gui_custom_container.
data : gs_layout TYPE lvc_s_layo.
在公益组织
IF delegationlist_container IS INITIAL.
* create a custom container control for our ALV Control
CREATE OBJECT delegationlist_container
EXPORTING
container_name = 'ALV_CONT'
EXCEPTIONS
cntl_error = 1
cntl_system_error = 2
create_error = 3
lifetime_error = 4
lifetime_dynpro_dynpro_link = 5.
* create an instance of alv control
CREATE OBJECT delegationlist_table
EXPORTING
i_parent = delegationlist_container.
* Set a titlebar for the grid control
gs_layout-grid_title = 'Délégations'.
gs_layout-sel_mode = 'A'.
gs_layout-cwidth_opt ='X'.
* set table as data source
* the struct name *must* be uppercase
* the table must have this struc
CALL METHOD delegationlist_table->set_table_for_first_display
EXPORTING
i_structure_name = 'ZPRT_DELEGATIONLIST'
is_layout = gs_layout
CHANGING
it_outtab = delegationlist.
ENDIF.
希望这有帮助,
