chk this

CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog           = it_fieldcatalog
    IMPORTING
      ep_table                  = new_table
    EXCEPTIONS
      generate_subpool_dir_full = 1
      OTHERS                    = 2.
  IF sy-subrc <> 0.
*  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*             WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.

  ASSIGN new_table->* TO <it_final>.

*********CREATE WORK AREA****************************

CREATE DATA new_line LIKE LINE OF <it_final>.
  ASSIGN new_line->* TO <wa_final>.

*********INSERTTING WORK AREAR TO INTERNAL TABLE******

    INSERT <wa_final> INTO TABLE <it_final>.

*******POPULATING DATA*******************************  
  LOOP.
   
   ASSIGN COMPONENT 'FIELD1' OF STRUCTURE <wa_final> TO <w_field>.
   <w_field> = '12345'.

    ASSIGN COMPONENT 'FIELD2' OF STRUCTURE <wa_final> TO <w_field>.
   <w_field> = '21453DD'.

   FIELD1 AND FIELD2 ARE COMPONENTS OF FIELDCATALOG.
    
ENDLOOP.

field-symbols: <l_field> type any .

loop at <gt_table> assigning <wa_table>.

assign component 'FIELDNAME' of structure <wa_table> to <l_field>.

if <l_field> is assigned .

<l_field> = 'some value' .

endif .

endloop.

You can access the fields using

<wa_table> - field_name.

Hi ..

I do not know how you have created the dynamic internal tables...

but just for your reference ... I am giving u a piece of code ... Its quiet simple ..

Say.. You want to change the 3rd column of the table. So to read the 3rd column, I write the statement : ASSIGN COMPONENT 3 OF STRUCTURE <fs_wa> TO <fs_val>.

Then on it is simple since I am using the Field symbols.

Just see in debugging mode and you will understand everything.

FIELD-SYMBOLS : <fs_table> TYPE ANY TABLE,

<fs_wa> TYPE ANY,

<fs_val> TYPE ANY.

LOOP AT <fs_table> ASSIGNING <fs_wa>.

ASSIGN COMPONENT 3 OF STRUCTURE <fs_wa> TO <fs_val>.

<fs_val> = 'Test Change'.

MODIFY TABLE <fs_table> FROM <fs_wa>.

BREAK-POINT.

ENDLOOP.

Feel free to contact in case it is not clear .. I can give u another example ..

Plz reward points if this was helpful ..
