ALV Grid 不刷新 [英] ALV Grid is not refreshed
问题描述
我的模块池程序中有两个屏幕(屏幕 A 和屏幕 B).屏幕A显示ALV网格,工具栏上有1个按钮,屏幕B也显示ALV网格和工具栏上的1个按钮.
I have two screens (screen A and screen B) in my module pool program. Screen A displays ALV grid and has 1 button on the toolbar and Screen B also displays ALV grid and 1 button on the toolbar.
当我按下显示订单"按钮时在屏幕 A 上,我被定向到屏幕 B.然后我在屏幕 B 上进行一些编辑操作,单击工具栏上的保存"按钮,然后单击返回"按钮.
When I press the button "Show orders" on screen A, I am directed to the screen B. Then I do some edit operations on screen B, click 'Save' button on the toolbar and then 'Back' button.
当我按下显示订单"按钮时在不同行的屏幕 A 上,我再次被定向到屏幕 B,但 ALV 网格仍然显示来自第一个材料的数据,即它不显示新数据,而是显示旧数据.
When I press the button "Show orders" on screen A for a different row, I am directed to the screen B again, but ALV grid still shows data from the first material, i.e. it doesn't display new data, but displays old data.
它是否与 cl_gui_cfw=>flush 方法有关?如果是,那么我应该在代码中的哪个位置调用它以显示正确的数据?
Does it have to do with cl_gui_cfw=>flush method somehow? If yes, then where exactly in the code should I call it in order to display correct data?
屏幕 B 的 PBO 模块.
PBO module of Screen B.
CREATE OBJECT zclmz_pp_md_create=>go_container_charg
EXPORTING
parent = cl_gui_container=>screen0
side = cl_gui_docking_container=>dock_at_top
extension = 800.
CREATE OBJECT zclmz_pp_md_create=>go_alv_charg
EXPORTING
i_parent = zclmz_pp_md_create=>go_container_charg.
zclmz_pp_md_create=>go_alv_charg->set_table_for_first_display( EXPORTING
is_layout = ls_layout CHANGING it_outtab = zclmz_pp_md_create=>gs_plz-
charg it_fieldcatalog = lt_fieldcat ).
屏幕 B 的 PAI 模块.
PAI module of Screen B.
zclmz_pp_md_create=>go_alv_charg->refresh_table_display( EXPORTING is_stable = ls_stable ).
CALL METHOD cl_gui_cfw=>flush.
推荐答案
refresh_table_display
方法应该在屏幕 B 的 PBO 中调用,而不是在 PAI 中.
Method refresh_table_display
should be called in the PBO of screen B, not in the PAI.
IF zclmz_pp_md_create=>go_alv_charg is NOT BOUND.
CREATE OBJECT zclmz_pp_md_create=>go_container_charg
EXPORTING
parent = cl_gui_container=>screen0
side = cl_gui_docking_container=>dock_at_top
extension = 800.
CREATE OBJECT zclmz_pp_md_create=>go_alv_charg
EXPORTING
i_parent = zclmz_pp_md_create=>go_container_charg.
zclmz_pp_md_create=>go_alv_charg->set_table_for_first_display( EXPORTING
is_layout = ls_layout CHANGING it_outtab = zclmz_pp_md_create=>gs_plz-
charg it_fieldcatalog = lt_fieldcat ).
ELSE.
zclmz_pp_md_create=>go_alv_charg->refresh_table_display( ).
ENDIF.
