ALV GRID + Program Errors

Former Member — Wed, 06 Dec 2006 12:05:22 GMT

Hello Friends,

I have written a program which calls a function module ( for further processing ), and at the end this function moduels displays the ALV-GRID. Everything looks okey, and the ALV Gribd is also displayed fine, But after the ALV Grid is displayed, and when I try to select one of the table entry and try to use the tool-bar functions ( details, sort, find, or filter ) the program shows me the error message, stating "STOP Program errors" and then program exits, any idea what's going on ?

Here is my code for ALV GRID.

DATA:

lv_custom_cont TYPE REF TO

cl_gui_custom_container,

galv_sel TYPE REF TO cl_gui_alv_grid,

ps_layout TYPE lvc_s_layo,

/cla/zz_lo_error TYPE dd02l-tabname,

ls_variant TYPE disvariant.

output ALV List

IF galv_sel IS INITIAL.

CREATE OBJECT galv_sel

EXPORTING i_parent = lv_custom_cont.

ls_variant-report = sy-repid.

ls_variant-username = sy-uname.

CALL METHOD

galv_sel->set_table_for_first_display

EXPORTING

i_structure_name = '/CLA/ZZ_LO_ERROR'

is_layout = ps_layout

is_variant = ls_variant

i_save = 'A'

CHANGING

it_outtab = it_update[].

it_fieldcatalog = pt_fieldcat
it_sort = pt_sort.

ELSE.

CALL METHOD galv_sel->refresh_table_display.

ENDIF.

Regards,

null

Hello Haider

The problem is the use of the function module (TABLES ?) parameter IT_UPDATE. Please remember that the data itab must be globally defined because its is a CHANGING parameter of the method SET_TABLE_FOR_FIRST_DISPLAY.

Try the following: define a global itab in the TOP include of your function group. Before calling method SET_TABLE_FOR_FIRST_DISPLAY move the itab values to this global itab like this:

  GT_UPDATE = it_update[].

Hello Uwa,

Thanks for your reply, now I have declared an includ, and place the declaration of it_update in this include, and I call this include at the first line of FM, but problem still there....

Any idea.....

Hello Vijay,

When I implement the functionality in single report then it usually works, but now I am facing this strange problem, and the senario is that from my program I call this fm, and inside this fm, I call the alv-grid for first display method etc.....

Any idea, why it works in single report and not in fm, and gives me this strange error msg.

Regards,

PS: if you provide me your mail id, I can send you the exact screen-shot of msg... send me mail at web_cheela@yahoo.com, ....
