ALV Grid - User Defined Buttons

Former Member — Mon, 14 Oct 2013 09:48:55 GMT

Hi there,

I am new to SAP and ABAP and this is my first time using SCN so hopefully someone can help me!

I am trying to change the standard buttons on an ALV grid. There seem to be a few different ways of doing this but the way I have been trying to implement involves copying the GUI Status from another program (I have tried using SAPLKKBL)

After successfully copying the GUI status I have added some code to set the status within my Z program (Z_CHANGE_ICONS_TEST).

I have followed the instructions in other discussions which advise to include a form to set the pf status and then to call the pf status using the parameter - i_callback_pf_status_set = 'ZSTANDARD' within the 'REUSE_ALV_GRID_DISPLAY'.

I have done all this but when I execute, the ALV toolbar disappears as does the standard SAP toolbar so I can't even back out to return to my code.

If i remove the i_callback_pf_status_set then the toolbar comes back but I have no control over the icons.

I'm sure there is a simple solution to my problem but a bit of help/advice would be much appreciated as I am rather stuck.

My code is copied below.

*&---------------------------------------------------------------------*

*& Report Z_ALV_CHANGE_ICONS_TEST

*&---------------------------------------------------------------------*

REPORT Z_ALV_CHANGE_ICONS_TEST.

*&---------------------------------------------------------------------*

*& Data Declaration

*&---------------------------------------------------------------------*

DATA: it_sflight TYPE TABLE OF sflight,

it_fieldcat TYPE slis_t_fieldcat_alv,

wa_fieldcat TYPE slis_fieldcat_alv.

*****************************************************************

* 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

*&---------------------------------------------------------------------*

*& START-OF-SELECTION

*&---------------------------------------------------------------------*

START-OF-SELECTION.

*Fetch data from the database

SELECT * FROM sflight INTO TABLE it_sflight.

*Build field catalog

wa_fieldcat-fieldname = 'CARRID'. " Fieldname in the data table

wa_fieldcat-seltext_m = 'Airline Code'. " Column description in the output

APPEND wa_fieldcat TO it_fieldcat.

*Pass data and field catalog to ALV function module to display ALV list

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

it_fieldcat = it_fieldcat

i_callback_pf_status_set = 'ZSTANDARD'

TABLES

t_outtab = it_sflight

EXCEPTIONS

program_error = 1

OTHERS = 2.

Read this (old) FM documentation, you forgot to pass parameter I_CALLBACK_PROGRAM with the program name containing the FORM for I_CALLBACK_PF_STATUS_SET, I_CALLBACK_USER_COMMAND (for your function codes), etc. (Don't use sy-repid here but move it first to another variable) - so ALV look for ZSTANDARD status of standard program, not much success.

Also the documentation suggested to use a copy of status STANDARD from function group SALV. (or program SAPLSALV) (very similar to the one you copied)

Raymond

Hi Raymond,

Thank you for your reply. I have tried using the status STANDARD from SAPALV also but having the same problem.

Could you possibly give me an example of how I should use the I_CALLBACK_PROGRAM and the I_CALLBACK_USER_COMMAND functions or post a link...I really am new to this and so I don't really understand your response.

Thanks in advance.

Steven

Check in your system for samples and demos with transaction DWDM and ABAPDOCU.
Using SCN search tool, you could find sample like ALV OM Template Program

Hallo Steve Allant:

Try this:

1. Update 'REUSE_ALV_GRID_DISPLAY' FM call to include 'USER_COMMAND' FORM

2. Create 'USER_COMMAND' FORM

in your progrma this should look like this:

*&---------------------------------------------------------------------*

*& Report Z_ALV_CHANGE_ICONS_TEST

*&---------------------------------------------------------------------*

REPORT Z_ALV_CHANGE_ICONS_TEST.

*&---------------------------------------------------------------------*

*& Data Declaration

*&---------------------------------------------------------------------*

DATA: it_sflight TYPE TABLE OF sflight,

it_fieldcat TYPE slis_t_fieldcat_alv,

wa_fieldcat TYPE slis_fieldcat_alv.

*****************************************************************

* 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

*&---------------------------------------------------------------------*

*& START-OF-SELECTION

*&---------------------------------------------------------------------*

START-OF-SELECTION.

*Fetch data from the database

SELECT * FROM sflight INTO TABLE it_sflight.

*Build field catalog

wa_fieldcat-fieldname = 'CARRID'. " Fieldname in the data table

wa_fieldcat-seltext_m = 'Airline Code'. " Column description in the output

APPEND wa_fieldcat TO it_fieldcat.

*Pass data and field catalog to ALV function module to display ALV list

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

it_fieldcat = it_fieldcat

i_callback_program = gd_repid ( this is your program in global_variable )

I_callback_user_command = 'USER_COMMAND' ( your form in your Report )

TABLES

t_outtab = it_sflight

EXCEPTIONS

program_error = 1

OTHERS = 2.

Then your report make so:

FORM 'USER_COMMAND'

case sy-ucomm

when 'xyz'

then something.

when 'abc'

the something'

endcase

ENDFORM.

Set break-point on case sy-ucomm. Sy-ucomm have the "ABAP" cod of ALV button.

Please reward if helpful

Kind Regards.

Marek.

hi steven

you can write in that i_call_back_pf_status form name(set_pf_status) not pf_status(zstandard) name and also u can write form pf_status at the end of program i.e after call fm reuse_alv_grid_display

Hall naven,

you can write in that i_call_back_pf_status form name(set_pf_status) not pf_status(zstandard) name and also u can write form pf_status at the end of program i.e after call fm reuse_alv_grid_display.

but form should be "set_pf_status" if i good understand. Not "pf_status". The same name , what is in i_call_back_pf_status ??

Marek.
