no data in ALV when using MC_STYLE_ENABLED

former_member183924 — Tue, 06 Feb 2007 10:30:09 GMT

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:

I also looked in the examples of BCALV_EDIT_0*.

Here is the code:

              txt2  = sy-subrc
              txt1  = 'Error in Flush ALV'(500).
  ENDIF.
ENDMETHOD.

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:


create data gs_table_row like es_table_row.

And the gs_table_row has the needed deep-structure.

After it i cannot see any really intressting backend-functions related to my Problem.

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 = 'ZMM_LAB_DISPO'

i_save = 'A'

it_toolbar_excluding = lt_exclude

is_layout = g_lvc_layout

CHANGING

it_outtab = it_lab_dispo3[]

REgards,

Ravi

ok I have found this number in the oss: 695910

and it means that SAP do not support such methods like: IS_READY_FOR_INPUT

and attribute MC_STYLE_ENABLED.

Steffen
