No toolbar buttons when using SLVC_FULLSCREEN with REUSE_ALV_GRID_DISPLAY

Question

I have written ABAP program by SAP Press book ABAP Basics listing 5.1 .

Everything is working fine except I am not able to display any icon for execute/delete operation which I added using slvc_fullscreen from reuse_alv_grid_display . I am not able to see even back button on the screen when I delete function. Any suggestions?

Answer 1

I don't know if I'm right but in the ' zptb00_hrc_delete ' form in the ' REUSE_ALV_GRID_DISPLAY ' function you set:

I_CALLBACK_PF_STATUS_SET = 'CB_ALV_PF_SET_STATUS'

However the ' CB_ALV_PF_SET_STATUS ' form doesn't exist. I think you misspelled the name of the form because there's a form called ' CB_ALV_PF_STATUS ' that seems to fit:

FORM cb_alv_pf_status USING rt_extab TYPE slis_t_extab.
  SET pf-status 'STANDARD_FULLSCREEN' EXCLUDING rt_extab.
ENDFORM.

Let's try changing that in the ' REUSE_ALV_GRID_DISPLAY ' call like this:

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      I_CALLBACK_PROGRAM       = l_dis-report

      I_CALLBACK_PF_STATUS_SET = 'CB_ALV_PF_STATUS' " ---> 'CB_ALV_PF_SET_STATUS' replaced by 'CB_ALV_PF_STATUS'

      I_CALLBACK_USER_COMMAND  = 'CB_ALV_USER_COMMAND'
      I_STRUCTURE_NAME         = 'ZPTB00_HRESERVAT'
      IS_LAYOUT                = l_str_layout
      I_DEFAULT                = 'X'
      I_SAVE                   = 'A'
      IS_VARIANT               = l_dis
    IMPORTING
      ES_EXIT_CAUSED_BY_USER   = l_str_exit_by_user
    TABLES
      T_OUTTAB                 = l_tab_reservationx
    EXCEPTIONS
      PROGRAM_ERROR            = 1
      OTHERS                   = 2.

I'm assuming that ' STANDARD_FULLSCREEN ' GUI status exists. Check that please.

Another observation is that in the form ' zptb00_hrc_show ' you are you using lowercase in the ' i_structure_name ' parameter in function ' REUSE_ALV_GRID_DISPLAY ' but it should be uppercase.

Instead of:

i_structure_name = 'zptb00_hreservat'

It should be:

i_structure_name = 'ZPTB00_HRESERVAT'

Hope it helps

Answer 2

In your line 161 you set:

SET pf-status 'STANDARD_FULLSCREEN' EXCLUDING rt_extab.

nmiranda assume that 'STANDARD_FULLSCREEN' GUI status exists. I assume it does not exist.

Can you open your report with SE38, display the code ad make a double click on STANDARD_FULLSCREEN . If you get a warning, that the status does not exist you identified the problem.

If the status exist: Did you define a button for delete?

If no -> define one. If you don't know how to do it, please post a comment. I will check if I can make a screenshot (sorry, actual I have no SAP available).

If you defined a button, please check i debugger the content of table rt_extab . If it contains the user command of your delete-action, then the button is suppressed. (I found nothing in your code, that fills the table, just to be sure).
