ASSIGN mt_outtab->* TO <tab1>.
  " assign local copy of initial line of <tab1> to <wa>.
  CREATE DATA l_dref_wa LIKE LINE OF <tab1>.
  ASSIGN l_dref_wa->* TO <wa>.

hi,

dinamic table create is like this, how can you create your mt_outtab->* table;

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = lt

IMPORTING

ep_table = <fs_data>

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

IF sy-subrc <> 0.

ENDIF.

*----

Assign Dyn Table To Field Sumbol

ASSIGN <fs_data>->* TO <tab1>.

CREATE DATA l_dref_wa LIKE LINE OF <tab1>.

ASSIGN l_dref_wa->* TO <wa>.

Check if Internal table is empty before you pass the value to the ALV tree FM / Method.

This shall avoid the dump.

I had the same problem. The code dumps when I tried to expand a node of the ALV tree.

Solution: You have to assign a GLOBAL internal table when using set_table_for_first_display.

CALL METHOD tree1->set_table_for_first_display

EXPORTING

it_list_commentary = lt_list_commentary

is_hierarchy_header = l_hierhdr

CHANGING

it_outtab = gt_output_init

it_fieldcatalog = gt_fieldcatalog.

if gt_output_init is local the code dumps.

if gt_output_init is global it works fine.

Thank you so much!

I was having the dump below, for a normal cl_gui_alv_grid->set_table_for_first_display, that I was calling inside a class from SE24 that I've created. The reason for the dump was excatly what you mentioned: My table was local to the method, and I had to change it to Global inside the class, in order to stop the dump. I don't understand why, but it worked!

The dump was:

GETWA_NOT_ASSIGNED
SAPLSLVC
BC-SRV-ALV

Field symbol has not yet been assigned.

Error in the ABAP Application Program

The current ABAP program "SAPLSLVC" had to be terminated because it has
come across a statement that unfortunately cannot be executed.

You attempted to access an unassigned field symbol
(data segment "-1").

"GETWA_NOT_ASSIGNED" " "
"SAPLSLVC" or "LSLVCU26"
"LVC_FILL_DATA_TABLE"

function lvc_fill_data_table .

assign mt_outtab->* to <tab1>.

mt_outtab freed stack
