ABAP refresh_table_display刷新ALV网格并保持位置(单元格行列位置不变)

1.方法一

FORM USER_COMMAND USING IW_UCOMM    TYPE SY-UCOMM
                        IS_SELFIELD TYPE SLIS_SELFIELD.
                        
  IS_SELFIELD-COL_STABLE = 'X'.		"列保持
  IS_SELFIELD-ROW_STABLE = 'X'.		"行保持
  IS_SELFIELD-REFRESH    = 'X'.			"是否刷新
ENDFORM.


1.方法二

FORM FRM_WHEN_CHANGED .
  DATA: IS_STABLE TYPE LVC_S_STBL.
  IS_STABLE-ROW = 'X'.	"保持行
  IS_STABLE-COL = 'X'.		"保持列

  CALL METHOD GV_GRID->REFRESH_TABLE_DISPLAY( EXPORTING IS_STABLE = IS_STABLE ).						"刷新
ENDFORM.

【ABAP系列】SAP ABAP 刷新SCREEN的方法 - 走看看

1:

* 显示ALV
CALL METHOD gr_alvgrid->set_table_for_first_display
* 刷新ALV
CALL METHOD gr_alvgrid->refresh_table_display

有2个参数,一个是行,一个是列.如果设置了相应的值,
那么对应的行,或者列,在刷新的时候,将会保持稳定,就是滚动条保持不动.

有些时候需要再调用 CL_GUI_CFW=>FLUSH方法,才能看到刷新后的结果。

2:

设置 selfield-refresh = 'X'

用的太多,不赘述。

cl_gui_cfw=>flush._闫艺宸的博客-CSDN博客

 CL_GUI_CFW=>FLUSH把更新后的数据同步到SAP GUI

用法一:
REFRESH_TABLE_DISPLAY虽然刷新的界面,但是SAP GUI并不是实时更 新,而是将更新的结果放在缓存中,手动调用CL_GUI_CFW=>FLUSH才能触发SAP GUI更新界面,看到刷新的结果。
CALL METHOD cl_gui_cfw=>flush
EXCEPTIONS
cntl_system_error = 1
cntl_error = 2.
用法二:
在OO的ALV方法中,使程序重新走PBO
CALL METHOD cl_gui_cfw=>set_new_ok_code
EXPORTING
new_code = ‘REFRESH’
CALL METHOD cl_gui_cfw=>flush.
用法三:
FORM frm_refresh_dlysk_display USING pv_p_refresh.
IF g_grid_dlysk IS INITIAL.
EXIT.
ENDIF.

Refresh grid
CALL METHOD g_grid_dlysk->refresh_table_display
EXPORTING
i_soft_refresh = pv_p_refresh.

CALL METHOD cl_gui_cfw=>flush.
ENDFORM. " FRM_REFRESH_DLYSK_DISPLAY

cl_gui_cfw=>flush

  用法一:

     REFRESH_TABLE_DISPLAY虽然刷新的界面,但是SAP GUI并不是实时更新,而是将更新的结果放在缓存中,手动调用CL_GUI_CFW=>FLUSH才能触发SAP GUI更新界面,看到刷新的结果。

  CALL METHOD cl_gui_cfw=>flush
    EXCEPTIONS
      cntl_system_error = 1
      cntl_error        = 2.

   用法二:

例如下面让用户选择文件夹的代码:

CALL METHOD cl_gui_frontend_services=>directory_browse
        CHANGING selected_folder = folder.
      CALL METHOD cl_gui_cfw=>flush.

why should we call the flush method?

here is some notes about this mehtod, from About cl_gui_cfw=>flush_xyfchris的博客-CSDN博客

"In OO approach, calling a Control-method does not imply that the method is automatically executed at runtime. Initially, the system buffers methods in a queue, referred to as the Automation Queue, when they are called in the ABAP program. The execution sequence of the methods therefore remains unchanged. However, the methods are only executed if they are transferred to the frontend via Remote Function Call (RFC) using method FLUSH. This means that the Automation Queue is used to reduce the number of RFC calls required."

用法三:

在OO的ALV方法中,使程序重新走PBO

  CALL METHOD cl_gui_cfw=>set_new_ok_code
    EXPORTING
      new_code = 'REFRESH'.

  CALL METHOD cl_gui_cfw=>flush.

CAN长字节DM1报文是指在CAN总线上传输的长度超过8个字节的DM1报文。根据引用\[1\],当要传输的数据长度超过8个字节时,首先使用TPCM进行广播,广播内容包含即将传输报文的PGN、总的数据包长度等信息,然后使用TP.DT进行数据传输。相邻两个TP.DT之间的时间间隔是50ms到200ms。根据引用\[2\],当字节数大于8时,将会使用多帧传输参数组。根据引用\[3\],DM1报文是Diagnostic Message 1, Active Diagnostic Trouble Codes的缩写,用于点亮故障指示灯、红色停机灯等,周期性播报控制器中处于激活状态的故障码。DM1报文的格式包括各个字节的定义,如故障指示灯、红色停机灯、琥珀色警告指示灯等。因此,CAN长字节DM1报文是指在CAN总线上传输的长度超过8个字节的DM1报文,用于传输更多的故障码信息。 #### 引用[.reference_title] - *1* [车载通信——J1939 DM1](https://blog.csdn.net/weixin_64064747/article/details/130193432)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^control_2,239^v3^insert_chatgpt"}} ] [.reference_item] - *2* [J1939广播DM1报文](https://blog.csdn.net/mengdeguodu_/article/details/108173263)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^control_2,239^v3^insert_chatgpt"}} ] [.reference_item] - *3* [J1939商用车在线诊断DM1报文](https://blog.csdn.net/traveller93/article/details/120735912)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^control_2,239^v3^insert_chatgpt"}} ] [.reference_item] [ .reference_list ]
