Clear Structure field in FOR loop in ABAP

Is there any way we can clear for loop structure fields in sap abap and return it back to new internal table.

  LOOP AT lt_a INTO DATA(ls_a).
    CLEAR: ls_a-f1, ls_a-f2.
    APPEND ls_a TO lt_n.
  ENDLOOP.

Can we achieve this scenario using FOR loop, Something like below?

lt_n = VALUE #( FOR <ls_a> IN LT_A ( f1 = '' f2 = '' ) ).

I need to send the complete structure <ls_a> with clear fields f1 and f2 to lt_n without mapping each field for <ls_a>.

Solution

  • I think this will do it, if the field names are the same:

    lt_n = VALUE #( FOR <ls_a> IN lt_a 
              ( CORRESPONDING #( <ls_a> 
                  MAPPING f1 = DEFAULT VALUE #( ) 
                          f2 = DEFAULT VALUE #( ) ) ).
