ALV Grid Display Protocol Error

chowdharyrohit1 — Mon, 04 Nov 2019 15:40:53 GMT

I am working on a editable ALV grid control. I have created a button for user to upload excel file. To trigger data_changed event following is coded:

DATA : lt_bad_cells TYPE lvc_t_modi,
lt_msg TYPE lvc_t_msg1.

IF go_obj->go_data_obj IS NOT BOUND. 
CREATE OBJECT go_obj->go_data_obj " Error handler object reference to cl_alv_changed_data_protocol

EXPORTING
i_calling_alv = go_grid. "ALV Grid 
ENDIF.

LOOP AT <fs_gt_read_table> ASSIGNING FIELD-SYMBOL(<fs_read>).
   IF <fs_read> IS ASSIGNED.
      MOVE-CORRESPONDING <fs_read> TO gwa_park_jou_it.
      INSERT gwa_park_jou_it INTO gt_park_jou_it INDEX lv_next.
      ls_mod_cell-row_id = sy-tabix.
      ls_mod_cell-tabix = sy-tabix.
      LOOP AT lt_fcat ASSIGNING FIELD-SYMBOL(<fcat>).
         ls_mod_cell-fieldname = <fcat>-fieldname.
         ASSIGN COMPONENT <fcat>-fieldname OF STRUCTURE <fs_read> TO FIELD-SYMBOL(<value>).
         IF sy-subrc = 0.
            ls_mod_cell-value = <value>.
            INSERT ls_mod_cell INTO TABLE gt_mod_cells.
         ENDIF.
      ENDLOOP.
      lv_next = lv_next + 1.
   ENDIF.
ENDLOOP.
CALL METHOD go_grid->refresh_table_display.
CALL METHOD go_grid->if_cached_prop~set_prop
     EXPORTING
        propname = 'GridModified'
        propvalue = '1'.
go_obj->handle_data_changed( er_data_changed = go_obj->go_data_obj
                                      sender = go_grid ).
go_obj->go_data_obj->display_protocol( ).

The messages are added as following in various check methods 

er_data_changed->add_protocol_entry( " In case of issue send error message
                 EXPORTING
                   i_msgid = text-038
                   i_msgno = lc_msgno
                   i_msgty = gc_e
                   i_msgv1 = text-011
                   i_msgv2 = lo_exe->get_text( )
                   i_fieldname = lv_good-fieldname
                   i_row_id = lv_good-row_id ).

In handle data changed method following is coded.

IF gt_mod_cells IS NOT INITIAL.
   INSERT LINES OF gt_mod_cells INTO TABLE er_data_changed->mt_good_cells.
   INSERT LINES OF gt_mod_cells INTO TABLE er_data_changed->mt_mod_cells.
   DATA(lv_no_value) = abap_true.
   REFRESH: gt_mod_cells.
ENDIF.
IF er_data_changed IS BOUND.
   er_data_changed->refresh_protocol( ).
ENDIF.

All is working fine. Error messages for data validations are being displayed as POPUP as well.

The issue which I am facing is that system generates an ABAP dump when protocol box is closed.

At close of protocol box event "on_close" is triggered which tries to set_focus to calling ALV.

The value of calling ALV is blank in the method set_focus of Cl_GUI_CONTROL.

When method go_obj->go_data_obj->display_protocol( i_calling_alv = go_grid ) is called with ALV Grid reference no messages are displayed.

Go_data_obj is defined as class-data.

Any help will be really appreciated. I am just having a black out for last few days to resolve this.
