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>.

Reset to default 1

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 #( ) ) ).

You may use BASE followed by the structured variable to set its initial value and followed by one or more field assignments to make the base vary. Documentation of BASE for structures: VALUE, Structures.

Demonstration:

TYPES: begin of ts_a,
         f0 TYPE string,
         f1 TYPE string,
       end of ts_a.
TYPES tt_a TYPE STANDARD TABLE OF ts_a WITH EMPTY KEY.

DATA(lt_a) = VALUE tt_a( ( f0 = 'F0' f1 = 'F1' ) ).

DATA(lt_n) = VALUE tt_a( FOR <ls_a> IN lt_a ( VALUE #( BASE <ls_a> f1 = '' ) ) ).

" Expected result:
ASSERT lt_n = VALUE tt_a( ( f0 = 'F0' f1 = '' ) ).
