mt_outtab error in ALV tree node expantion

[Karan_Chopra_]

I ahve made tree ALC n get dump in the follwing code when I expand any node

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>.

this is because mt_outtab->* does no have values which is my table

dont know how its freed on expanding the node

I made a same prog from a system program n thats working fine but i cannot get the diffrence???

plz help

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>.

How to go for it

this mt_outtab has free memory when ever I all some event for which method is in class definition

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.
