Add Button to ALV Toolbar with REUSE_ALV_LIST_DISPLAY
In the program which calls ALV using REUSE_ALV_LIST_DISPLAY,
I have to add a new button.
I saw the demo program BCALV_GRID_08, which is written using ABAP-Controls.
In that example, the button is added using TOOLBAR event of cl_gui_alv_grid.
Could you help me to implement the same logic using REUSE_ALV_LIST_DISPLAY parameters.
Please follow the below steps:
- You should copy the 'STANDARD' GUI status from program SAPLKKBL using transaction SE90 -->Programming SubObjects--> Gui Status.
- Execute this transaction to get to next screen. select status using checkbox. click on GUI Status --> Copy.
- Enter your Z program name and the name you what for this status - you can keep it as 'STANDARD' to be simple.
- Then you can edit the new status to add or delete buttons. This will also bring in the standard SAP ALV functionality such as sorting/subtotaling etc...
- When you call 'REUSE_ALV_GRID_DISPLAY' make sure you pass it the new status name.
An example of one of mine:
call function 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
i_callback_program = 'ZSDBOLST_REPORT'
i_callback_pf_status_set = 'STANDARD' <---------
i_callback_user_command = 'USER_COMMAND'
i_structure_name = 'I_BOLACT'
i_grid_title = 'BOL Action Report'(031)
is_layout = gs_layout
it_fieldcat = gt_fieldcat[]
i_save = 'A'
is_variant = v_variant
TABLES
t_outtab = i_bolact
EXCEPTIONS
program_error = 1
others = 2.
I just tried the same procedure ,but my entire application toolbar disappeared and a lock icon appears next to the application toolbar in my copied pf-status.
Could you advice what might have gone wrong ?
As identified with the FM's help you can do the following.
1). Using SE80 (I think) you can copy a GUI status from one program to another. It mentions which one in the FM's help.
2). Create a form named like so:
Code:
*****************************************************************
* Form Set_pf_status
* Notes: Called by FM REUSE_ALV_GRID_DISPLAY
*****************************************************************
FORM set_pf_status USING rt_extab TYPE slis_t_extab.
SET PF-STATUS 'ZSTANDARD'.
ENDFORM. "Set_pf_status
In the above case the GUI status copied was named ZSTANDARD and adjusted accordingly, adding and removing the desired buttons. A button was added called '%DELETE'.
3). Create the following report:
Code:
*****************************************************************
* Form User_command
* Notes: Called by FM REUSE_ALV_GRID_DISPLAY
* Detects whether the icon/button for
* 'Return Tag Deletion' has been pressed. If it has then
* detect whether any rows have been highlighted and then
* set the delete flag.
*****************************************************************
FORM user_command USING r_ucomm LIKE sy-ucomm
rs_selfield TYPE slis_selfield.
DATA: li_count TYPE I.
IF r_ucomm EQ '%DELETE'.
LOOP AT %g00 WHERE mark EQ 'X'.
ADD 1 TO li_count.
ENDLOOP.
IF li_count GT 0.
gc_delete_flag = 'X'.
r_ucomm = '&F03'. "Back arraow
ELSE.
MESSAGE W000 WITH 'Please highlight the rows to be deleted!'.
ENDIF.
ENDIF.
ENDFORM. "User_command
As I've added an extra button to indicate which records should be deleted I need to identify a form to be called to process when this button is chosen.
Then when you call the ALV function you to specify the following extra details:
Code:
call function 'REUSE_ALV_GRID_DISPLAY'
exporting i_callback_program = gc_repid
I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS'
I_CALLBACK_USER_COMMAND = 'USER_COMMAND'
i_grid_title = lc_grid_title
is_layout = lc_layout
it_fieldcat = gt_fieldcat
it_sort = sort
i_save = l_save
is_reprep_id = l_bbs_id
is_variant = l_variant
tables t_outtab = %g00
exceptions program_error = 1
others = 2.
The parameters in capitals are the extra ones that need to be added.
