Here is pseudo code. I'd probably not code like that, but I don't know your exact logic.

DO.
  repeat_loop = abap_false.
  LOOP AT itab ... WHERE ...
    IF ...
      repeat_loop = abap_true.
      EXIT. " leave LOOP AT to go back to first record and resume first line
    ENDIF.
  ENDLOOP.
  IF repeat_loop = abap_false.
    EXIT. " leave DO
  ENDIF.
ENDDO.

sandra.rossi and what about replace LOOP with a READ... INDEX ... ?

sandra.rossi I said that "I'd probably not code like that" because "I don't know your exact logic", so any proposal could be valid. I hope that my comment will help the OP to elaborate the question.

Ok, i will make an simple example;
the following loop is on row 10 of the table and if statement is okay. I mark to lv_az_ok. now i have to go back for the first line. (my process is similar but of course there is a more complex calculation)

select * from sflight into table @data(t_sflight).<br>loop at t_sflight into data(_sflight).
  IF _Sflight-carrid = 'AZ'.
    DATA(lv_az_ok)  = 'X'.
     "leave LOOP AT to go back to first record and resume first line</em>
  ENDIF.
endloop.

Also, the above code is a solution for me. However, i'am still curious about your choice. Maybe this could be the new syntax. And no suitable for me read table or index.
