Concatenate Primary Key Fields of an internal table into a String.

Question

Hi,
I have a dynamic internal table created.
In the dynamic internal table,
How to concatenate all the primary keys of that row concatenated into a string and non primary keys into a different string.
Can some one help me on this.
E.g:
Itab1 has 3 Primary fields and 3 Non primary key fields and it has 2 records.
Table     col1     col2     col3     col4     col5     col6
Row1     AA     AB     AC     1     2     3
Row2     ZA     ZB     ZC     1     2     3
The following is needed.
Itab2 will have the concatenate strings
                   Key                               Nkey
Row1        AAABAC                      010203
Row2        ZAZBZC                       010203
Thanks,
Chaithanya

C,
Try something like this -  Use an ASSIGN in a LOOP:
  data: lv_PK type string.
  data: lv_non_PK type string.
  field-symbols: lv_str type string.
  assign local copy of initial line of gt_table to <ls_table>.
  loop at gt_table.  " this is your table.
    do n times.  " n = 6 in your case
      if n < 4.
         assign component sy-index of structure <ls_table> to <lv_str>.
         concatenate <lv_str> to lv_PK.
   else.
         assign component sy-index of structure <ls_table> to <lv_str>.
         concatenate <lv_str> to lv_Non_PK.
     endif.
    enddo.
    append <ls_table> to <gt_table>.
  endloop.
