ABAP LOOP into work area with no result leave function

Question

I'm working on function module and I'm in trouble with my loop statement. My problem is, when nothing is found in this loop (this case needs to be handled) the program ends directly to endfunction and my else condition on bottom is not triggered.

Can someone explain me how to run my code even if no result is found in my loop? I'm hard stuck.

Thanks :)

  LOOP AT it_p0015 INTO ls_p0015 WHERE
  subty = iv_sty      AND
  betrg = iv_amount   AND
  endda = iv_end_date AND
  begda = iv_start_date.
        CALL FUNCTION 'ENQUEUE_EPPRELE'
      EXPORTING
        pernr          = iv_employeepernr "is_request-employeepernr
        infty          = '0015'
        subty          = iv_sty

ENDLOOP.
  ENDIF.

First, you could always see if sy-tabix has a value set, that's an indicator of the current line in the loop. Personally, if you're struggling I would just set a variable in the loop that's set so you know if it ran or not.

i.e.

    lv_loop = 0.    
    LOOP AT it INTO ls WHERE.
      lv_loop = 1.
    ENDLOOP.
    IF lv_loop = 0. "code didn't run
      "handle case
    ENDIF.
