I have an ALV grid with an editable field, if I check the data entered and display errors, the ALV updates, if I try to change the input data, other times the ALV does not update anymore.
The code in the PAI is:
ls_layout-cwidth_opt = abap_true.
CREATE OBJECT go_alv
EXPORTING
i_parent = cl_gui_custom_container=>screen0
EXCEPTIONS
error_cntl_create = 1
error_cntl_init = 2
error_cntl_link = 3
error_dp_create = 4
OTHERS = 5.
IF sy-subrc EQ 0.
* Adapting field catalog
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
EXPORTING
i_structure_name = 'ZAMOUNT'
CHANGING
ct_fieldcat = lt_fieldcat.
IF sy-subrc EQ 0.
* Field catalog specifics
LOOP AT lt_fieldcat ASSIGNING <ls_fieldcat>.
IF <ls_fieldcat>-fieldname = 'DMBTR'.
<ls_fieldcat>-edit = abap_true.
ENDIF.
ENDLOOP.
ENDIF.
* Show data usig ALV class
go_alv->set_table_for_first_display(
EXPORTING
is_layout = ls_layout
CHANGING
it_outtab = gt_out
it_fieldcatalog = lt_fieldcat ).
go_alv->set_ready_for_input( EXPORTING
i_ready_for_input = 1 ).
CALL METHOD go_alv->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_enter.
CALL METHOD go_alv->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_modified.
ENDIF.
The code in the PBO is:
IF go_alv IS NOT INITIAL.
CALL METHOD go_alv->check_changed_data( ).
PERFORM check_amounts TABLES gt_out
CHANGING gv_sum_amounts
gv_tot_amount.
CALL METHOD go_alv->refresh_table_display
EXPORTING
is_stable = VALUE #( row = abap_true
col = abap_true )
i_soft_refresh = 'X'.
cl_gui_cfw=>flush( ).
ENDIF.
In the perform check_amounts I populate a field of the ALV with the errors, if the user modifies the input field and the error is removed in the internal table but it is not shown in the ALV.
I also tried to implement the data_change_finished method by calling the refresh inside but I have not solved the anomaly.
Can you help me? Thanks
I'm not quite sure if I understand your problem but here are some potential issues I see:
I'd try to define a local class to handle the data_changed and data_changed_finished events and put the check_amount and refresh in the method for the data_changed_finished event. Maybe some of this helps you? If you have any questions about any of this, let me know and I can go into more detail.
