ALV

Former Member — Mon, 13 Feb 2006 08:02:39 GMT

Hi all,

I have a dropdown box in ALV display for which i Have addded a field catalog as below

field_cat-fieldname = 'DP_DOWN'.

field_cat-tabname = 'T_COMMIT'.

field_cat-coltext = 'Reason'.

field_cat-lowercase = 'X'.

field_cat-edit = 'X'.

field_cat-outputlen = 30.

APPEND field_cat TO ix_fldcat.

CLEAR field_cat.

I am populating the dropdown with the method

CALL METHOD go_grid->set_drop_down_table

EXPORTING

it_drop_down_alias = lt_dral.

READ TABLE ix_fldcat ASSIGNING <ls_fcat>

WITH KEY fieldname = 'DP_DOWN'.

IF sy-subrc EQ 0.

<ls_fcat>-drdn_field = 'HANDLE_DRDN'.

<ls_fcat>-drdn_alias = 'X'.

<ls_fcat>-drdn_hndl = 1.

ENDIF.

Now I am trying to make the change in the dropdown and save the list in to a table.

When i make a change in the drop down and move the cursor the program is going to short dump field symbol not assigned.

Kindly let me know whther i should use any other methods to capture the change.

I have already used the method data_change and populating the data without the dropdown.

i am getting error when i add the field of drop down.

Urgent.

Rewards will be given.

Thanks in antisipation.

regards,

Bala

Hi Raja,

For me i'm able to capture the data after change, using the event

HANDLE_DATA_CHANGED FOR EVENT DATA_CHANGED
                         OF CL_GUI_ALV_GRID
                         IMPORTING ER_DATA_CHANGED
                                   E_ONF4
                                   E_ONF4_BEFORE
                                   E_ONF4_AFTER.

but i'm not getting any error.

even i refresh what ever i choose it from drop down,it staying there only...

there is some probelm with your fieldcat, why are you modifying the fieldcat after , why can't you do it together. check my fieldcat...

Have tried checking the program BCALV_EDIT_06

Re: ALV

Former Member — Mon, 13 Feb 2006 09:09:06 GMT

hi,

from your code i can see one thing..

I am populating the dropdown with the method

CALL METHOD go_grid->set_drop_down_table
EXPORTING
it_drop_down_alias = lt_dral.

<b>READ TABLE ix_fldcat ASSIGNING <ls_fcat>
WITH KEY fieldname = 'DP_DOWN'.
IF sy-subrc EQ 0.
<ls_fcat>-drdn_field = 'HANDLE_DRDN'.
<ls_fcat>-drdn_alias = 'X'.
<ls_fcat>-drdn_hndl = 1.
ENDIF.</b>

see the bold one , here is some problem..

instead of this try...this way..

field_cat-fieldname = 'DP_DOWN'.
field_cat-tabname = 'T_COMMIT'.
field_cat-coltext = 'Reason'.
field_cat-lowercase = 'X'.
field_cat-edit = 'X'.
field_cat-outputlen = 30.
<b>field_cat-drdn_field = 'HANDLE_DRDN'.
field_cat-drdn_alias = 'X'.
field_cat-drdn_hndl = 1.</b>
APPEND field_cat TO ix_fldcat.
CLEAR field_cat.
