No data in ALV when using MC_STYLE_ENABLED

Question

Hi experts,
I want to display some data in a ALV-Grid control, with just one column which is editable. So the ALV-Grid looks well, when I only display the data. But when I add the attributes for the editable column into my internal table, then I cannot see any data in there. But I can see the rows with the editable column.
Here are the operations:
1) All items of an transparent table is viewed in the ALV-LIST1
2) User can select the specific rows which he/she want to edit.
3) User press a button in the toolbar of ALV-LIST1
4) The ALV-LIST2 comes up with the selected rows and one editabled column, but no data in there...
I already looked in this great example, but I cannot see any special command, posted here:
editing alv output
I also looked in the examples of BCALV_EDIT_0*.
Here is the code:

<b>If I follow my coding by processing the application, I could see that in the Method "SET_VALUES (CL_ALV_VARIANT)" which was executed by "CALL METHOD alv_list2->set_table_for_first_display" the table "it_outtab" is just filled with the data of my selected rows!
And after this Method their called "FUNCTION K_KKB_PUT_GLOBALS" which has only one command: </b>
create data gs_table_row like es_table_row.
<b>And the gs_table_row has the needed deep-structure.
After it i cannot see any really intressting backend-functions related to my Problem.
</b>
I also try to do something with the fieldcatalog but in this case I only could add columns to the existing table which was editable.

Steffen

Hi Steffen,
   Just give the name in capital letters and try:
display the second grid
  CALL METHOD alv_list2->set_table_for_first_display
       EXPORTING i_structure_name      = <b>'ZMM_LAB_DISPO'</b>
                 i_save                = 'A'
                 it_toolbar_excluding  = lt_exclude
                 is_layout             = g_lvc_layout
       CHANGING
                 it_outtab             = it_lab_dispo3[]
