Populating Dynamic Internal Table ?

Former Member — Thu, 29 May 2008 14:20:13 GMT

Hello All,

I have the fieldcatalog and from this I have creted a dynamic internal table like this :


* Create Dynamic Table
  CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = lt_fcat[]
    IMPORTING
      ep_table        = dy_table.
  ASSIGN dy_table->* TO <dyn_table>.

* Create Dynamic Work Area and Assign to FS
  CREATE DATA dy_line LIKE LINE OF <dyn_table>.
  ASSIGN dy_line->* TO <dyn_wa>.

I have my data in one of the internal table (ITAB).

Now I want to populate the dynamic internal table <fs_tab> with that data in the other internal table (itab) .

For this I guess I need to use ASSIGN COMPONENT Statement.

But I'm not able to decide upon how to do that.

For eg. :-

1. Say my internal table (ITAB) has 5 fields f1,f2,f3,f4,f5.

2. My Dynamic INternal table <fs_tab> has 3 fields f1,f3,f5 (from the above code).

3. Now I want to populate this dynamic table with the data from the Internal table ITAB for those particular 3 fields (f1,f3,f5).

How to pass the data to the dyntab ?

Request you all to clarify.

PS: PLease don't send me any links as I already read them but cudn't get thru it!

Simple way is to create a work area for the dynamic table and populate the work area using move-corresponding and append the dynamic internal table.

as shown below:


  data: l_wa_ref type ref to data.
  field-symbols:
  <l_wa_f_data> type any.

  create data l_wa_ref like line of <f_data>.
*Assign the work area
  assign l_wa_ref->* to <l_wa_f_data>.
  check sy-subrc = 0.

  loop at i_final2 into wa_final2.

    move-corresponding wa_final2 to <l_wa_f_data>.
* etc etc

  endloop.

Hello Sourav,

I did the same but it's going for a dump saying :

" Incorrect type of operand with the MOVE-CORRESPONDING statement."

Any other clues ?

  CREATE DATA dy_line LIKE LINE OF <dyn_table>.
  ASSIGN dy_line->* TO <dyn_wa>.

DATA: FIELDNAME(3) TYPE C.

FIELD-SYMBOLS: <FS_FIELD_FROM>, 
                            <FS_FIELD_TO>.

LOOP AT ITAB.
    
   DO 3 TIMES.
     WHEN 1. FIELDNAME = 'F1'.
     WHEN 2. FIELDNAME = 'F3'.
     WHEN 3. FIELDNAME = 'F5'.
    ASSINGN COMPONENT FIELDNAME OF STRUCTURE ITAB TO <FS_FIELD_FROM>.
    ASSINGN COMPONENT FIELDNAME OF STRUCTURE <DYN_WA> TO <FS_FIELD_TO>.
    <FS_FIELD_TO> = <FS_FIELD_FROM>.
   ENDDO.
   APPEND  <DYN_WA> TO <dyn_table>.
ENDLOOP.
