CREATING DYNAMIC INTERNAL TABLE WITHOUT FINAL STRUCTURE

[former_member574106]

Hi friends,

I am making my first dynamic internal table. The issue, is that I need to create a final internal table consisting of vkorg, erdat, material, posnr, menge, kunnr, without creating a user defined structure. How do I do it. please suggest. check the code once. 
REPORT zdynamicoops.
TABLES : vbak.
SELECT-OPTIONS : so_vkorg FOR vbak-vkorg,
                 so_erdat FOR vbak-erdat.
DATA : it_vbak TYPE TABLE OF vbak WITH HEADER LINE,
       it_vbap TYPE TABLE OF vbap WITH HEADER LINE.


DATA : gt_dyn_table TYPE REF TO data,
       gw_line TYPE REF TO data,
       gw_line1 TYPE REF TO data.


SELECT vbeln
       vkorg
       erdat
       kunnr
       FROM vbak
       INTO CORRESPONDING FIELDS OF TABLE it_vbak
       WHERE vkorg IN so_vkorg.

IF NOT it_vbak[] IS INITIAL.
SELECT vbeln
       posnr
       matnr
       zmeng
       FROM vbap
       INTO CORRESPONDING FIELDS OF TABLE it_vbap
       FOR ALL ENTRIES IN it_vbak
       WHERE vbeln EQ it_vbak-vbeln.
ENDIF.

Hi!

It might be just me, but I don't really understand what it is you want to do...

What do you mean in this case with 'dynamic internal table' and 'final internal table'? And if you know the fields for the 'final internal table', why would you not specify them in a structure? (Or were those fields just an example)

(Also, instead of selecting from VBAK and then FOR ALL ENTRIES in VBAP, a better approach is to JOIN the two tables)

Hi Jorgen,

Thanks a lot. I have written the code. In the output a small issue is coming. the 2nd line in the internal table is not coming in the next row. Please check the output and the code.output.jpg

Better never use cl_alv_table_create=>create_dynamic_table, it has important drawbacks, instead use RTTS with CREATE DATA. If you're lazy, use RTTS alternative via Z wrapper method which has same interface as cl_alv_table_create=>create_dynamic_table https://blogs.sap.com/2019/11/16/alternative-to-cl_alv_table_createcreate_dynamic_table/.

zcl_alv_table_create_rttc=>create_dynamic_table( ... ).

I really don't see why you're doing this in such a complicated way. You're also using a few obsolete ABAP statements (TABLES, HEADER LINE), and old techniques. Try this modern version.

You really don't need a dynamic table.
