Create_dynamic_table does not work when fieldcatalog table contains LVC_S_S

[Sougata]

I'm getting short-dump when creating dynamic internal table via CALL METHOD cl_alv_table_create=>create_dynamic_table. The fieldcatalog contains a component named LVC_S_STYL which populates fine when after call function LVC_FIELDCATALOG_MERGE but when this is passed to cl_alv_table_create=>create_dynamic_table it short dumps!

Is it possible to pass the style catalog in this case, how? Below is my code.

Structure of 'ZZ_ALV_FCAT' is WERKS type werks_d, DATE type datum, CELLTAB type LVC_S_STYL.

   CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
     EXPORTING
       i_structure_name             = 'ZZ_ALV_FCAT'
      CHANGING
        ct_fieldcat                  = lt_fieldcat.

    CALL METHOD cl_alv_table_create=>create_dynamic_table
      EXPORTING
        it_fieldcatalog           = lt_fieldcat
        i_length_in_byte          = ''
      IMPORTING
        ep_table                  = dy_table
      EXCEPTIONS
        generate_subpool_dir_full = 1
        OTHERS                    = 2.

    IF sy-subrc EQ 0.
      ASSIGN dy_table->* TO <dyn_table>.
    ELSE.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                 WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.

<b>I'll be generously giving away points for any help!</b>

Any idea anyone? I was thinking may be convert the HEX data to CHAR before creating the dynamic table then again convert the CHAR data back to HEX before I call SET_TABLE_FOR_FIRST_DISPLAY? In that case, how to convert Hex of a structure to CHAR and vice versa?

Hello Sougata

ALV list attributes like LVC_S_STYL need not (must not) be part of the fieldcatalog.

If you want to have an example of how to create such a complex itab dynamically have a look at:

Hi Uwe,

I added the following in your code after:

" Show how to fill the complex itab PERFORM fill_celltab.

PERFORM fill_celltab.

END-OF-SELECTION.

  TRY.
      CALL METHOD cl_salv_table=>factory
        IMPORTING
          r_salv_table = go_table
        CHANGING
          t_table      = <gt_itab>.
      go_table->display( ).
    CATCH cx_salv_msg .
  ENDTRY.

But column BUKRS is still not editable! What do you think the problem is?

Thanks.

Hello Sougata

As far as I know class CL_SALV_TABLE is not intended for editable ALV lists.

Why?

Have you ever seen an event similar to DATA_CHANGED of CL_GUI_ALV_GRID?

Conclusion:

- Non-editable ALV lists -> use CL_GUI_ALV_GRID or CL_SALV_TABLE

- Editable ALV lists -> use CL_GUI_ALV_GRID

Hi Uwe,

Then why do you do

ls_cell-style     = cl_gui_alv_grid=>mc_style_enabled.

in your program?

I'm using CL_GUI_ALV_GRID but passing dynamic table to it when I call SET_TABLE_FOR_FIRST_DISPLAY. Your program is quite complex and will take time to implement (and I'm running out of time fast!) Any quick way to populate the values of Celltab to a dynamic table?

Thanks.

Hello Sougata

I have used class CL_SALV_TABLE just for displaying the results of the dynamic itab creation. The purpose of routine FILL_CELLTAB is just to show that we are able to create a complex itab (record contains one field (CELLTAB) which itself is a table type) and how to fill it because this has to be done dynamically, too.

If the dynamically created itab is used for an editable ALV list then you must use CL_GUI_ALV_GRID.

I worote this code in my system (4.6C) and I got any dump:

I've included the structure LVC_S_STYL in my structure ZLVC_S_STYL and then add some fields.

But if I insert a field CELL like LVC_S_STYL, instead of to include it directly, I get the dump.

So I believe it depends on how you've defined the structure in dictionary, because in the second case it seems the METHOD can't create the subroutine to create the dynamic table.

It seems if it uses a complex structure where a field is a structure, the METHOD can't write a right defintion of an internal table based on the dictionary structure.

In my system I saw the method try to create a subroutine where the interna table is defined in this way:

DATA: STYLE TYPE ZLVC_S_STYL-STYLE.

instead of

DATA: STYLE TYPE ZLVC_S_STYL-CELL-STYLE.

Hi,

Can you send me the code for defining the Structure of 'ZZ_ALV_FCAT' ?
