ALV issue

Former Member — Tue, 25 Aug 2009 11:43:37 GMT

Hi All,

I have displayed the list through REUSE_ALV_GRID_DISPLAY, the first field I have added a check box in the internal table, now I want to select the line by selecting the check box and save in the internal table for further processing.

How I can do it?

Thanx

while populating FIELDCATALOG follow this code:

WA_FCAT-SELTEXT_L = 'Select'.

WA_FCAT-COL_POS = '1'.

WA_FCAT-FIELDNAME = 'CHECK'.

WA_FCAT-CHECKBOX = 'X'.

WA_FCAT-TABNAME = 'ITAB'.

WA_FCAT-OUTPUTLEN = '6'.

WA_FCAT-INPUT(1) = 'X'.

WA_FCAT-EDIT(1) = 'X'.

APPEND WA_FCAT TO FCAT.

CLEAR WA_FCAT.

Hi,

You will need to have the name of the variable defined in your internal table for the checkbox same as the new field that you will add through the fieldcatalog as mentioned in the previous post. Now you need to do some processing on the records selected through the checkbox. You must be doing so on the click of a button or so. You will have to define a subroutine say USER_COMMAND and pass the same to the parameter I_CALLBACK_USER_COMMAND in the FM REUSE_ALV_GRID_DISPLAY and inside this subroutine, you can use the code

loop at <internal table> where <checkbox fieldname> = 'X'.

do processing

endloop.

If you are allowing processing on only onle record at a time you can replace the loop with read statement.

Hope this helps

Regards

Sachin

Hi,

Suppose you have a custom button in your toolbar and after selecting some of the rows using checkbox you want to click that button in order to carry on further processing.If the scenario like this then

1)create PF-STATUS at first and set it in your ALV display

by setting the parameter i_callback_pf_status_set = 'PF_STATUS_SET' (in this way where 'PF_STATUS_SET' is the name of a subroutine)(search to learn how to create custom PF-STATUS from a standard one )

write the subroutine in this way

FORM pf_status_set USING rt_extab TYPE slis_t_extab.

SET PF-STATUS 'ZSTANDARD' OF PROGRAM 'ZSAR_ASSGN1_GRIDALV'.

ENDFORM. "pf_status_set

2) also set the parameter i_callback_user_command = 'USER_COMMAND'

USER_COMMAND is also an subroutine

write this subroutine in the following way

FORM user_command USING I_r_ucomm LIKE sy-ucomm

rs_selfield TYPE slis_selfield

WHEN '&XZZ'.

CLEAR l_cntr.

LOOP AT IT_final INTO WA_final.

IF WA_final-chk = 'X'."CHK is the name of the checkbox

l_cntr = l_cntr + 1.

ENDIF.

ENDLOOP.

IF l_cntr GT 1.

" Perform the task here

ENDIF.

ENDFORM.

Regards.

Hi Dharmendra Pewa,

Try the following:

DATA: ref_grid TYPE REF TO cl_gui_alv_grid.

IF ref_grid IS INITIAL.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = ref_grid.

ENDIF.

IF NOT ref_grid IS INITIAL.

CALL METHOD ref_grid->check_changed_data.

ENDIF.

This will update the check box in the internal table.

Hope this information is help to you.

Regards,

José

hi dharmendra ,

Refer to this link's sample program

1. have a pramter in the selection screen for variant.
