Back button

Former Member — Thu, 10 Apr 2008 07:55:19 GMT

Hi experts!

Im having a problem in my back button.

In my select all and deselect all button its working properly this is my code at user-command form.

WHEN 'SELECT'.

LOOP AT it_ltak INTO wa_ltak.

wa_ltak-sel = 'X'.

MODIFY it_ltak FROM wa_ltak TRANSPORTING sel.

ENDLOOP.

PERFORM alv_display_list.

it might be the cause why everytime I click the back button it repeats the history of how many times I click the checkbox or the select all button.

could you help me on how would I fix my problem?

My problem is everytime I click the back button it repeats the screen where I click the select all button.example i thick the select all button then deselect it then manually select any checkbox.then I decided to click the back button.when I click the back button it will repeat the things I did before I click the back button.do you have any idea on how would I fix it?

in my code in user-command in select all button and deselect and back button.

form user-command.

WHEN 'SELECT'.

LOOP AT it_ltak INTO wa_ltak.

wa_ltak-sel = 'X'.

MODIFY it_ltak FROM wa_ltak TRANSPORTING sel.

ENDLOOP.

WHEN 'DESELECT'.

LOOP AT it_ltak INTO wa_ltak.

HI,

For this you need to refresh the screen...

WHEN '&BCK'.

DATA ref1 TYPE REF TO cl_gui_alv_grid.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = ref1.

CALL METHOD ref1->check_changed_data.

CALL METHOD ref1->refresh_table_display.

LEAVE TO SCREEN 0.

endform.

Pls . reward if useful....

As far as i can get you from the mail is it repetion of data coming into your internal table ?

when 'SELECT '

REFRESH it_ltak[].

MODIFY/INSERT INTO O/P TABLE ..

to avoid the repetition of data into an internal table use refresh on that particular table .
