Workarea field is changing to ********* when i use at new command

Question

Hi All,
I have a workarea. In that work area i have a field (zsample -zbill_zrass). I am using  at new statement.
My problem is when i debug the code, am able to see that when the control goes inside at new statement, my field (zsample -zbill_zrass). which is holding a number is changing into ***********.  I have attached the code below for your reference.
Please help me to solve this issue.
loop at lt_zsample[] into wa_ zsample.
      clear wa_usr_addr.
      read table it_usr_addr into wa_usr_addr
                        with key accnt = zsample -zbill_zrass.
      if sy-subrc = 0.
        CONCATENATE lv_string zsample -zbill_zreff into wa_temp-zbill_zreff
                       SEPARATED BY space.
        wa_temp-zbill_zrass   = zsample -zbill_zrass.
        wa_temp-accnt        = wa_usr_addr-accnt.
        wa_temp-smtp_addr    = wa_usr_addr-smtp_addr.
        lv_temp = lv_string.
        lv_string = wa_temp-zbill_zreff.
        at new zbill_zrass.   -
>  when control goes inside this (at new ) my problem occurs
          clear lv_string.
          if lt_temp is not initial.
            describe table lt_temp lines lv_line.
            read table lt_temp into wa_temp index lv_line .
            if sy-subrc is initial.
              wa_temp-zbill_zreff = lv_temp.
              modify lt_temp index lv_line from wa_temp TRANSPORTING zbill_zreff.
            endif.
            clear wa_temp.
          endif.
          wa_temp-zbill_zreff  = wa_ zsample -zbill_zreff.
          wa_temp-zbill_zrass   = wa_zsample -zbill_zrass.
          wa_temp-accnt        = wa_usr_addr-accnt.
          wa_temp-smtp_addr    = wa_usr_addr-smtp_addr.
          lv_string = wa_temp-zbill_zreff.
          append wa_temp to lt_temp.
          clear wa_temp.
        endat.
      endif.
clear wa_sample.
endloop.

Hi, Mohamed Aslam 
Suppose you have the following Internal Table.
Field1 Field2 Field3
When ever you will use AT NEW, AT END or AT LAST mean any of Control Break Statement one the Field1 you will find all the Fields on the right hand side of that field as *** Stars in it, Suppose if you will use these all on Field2 than Field1 OK Field2 will also be OK but Field3 will again have Stars to over come this you can define a new work are and just before going into these Statement's Blocks assigns the current work area to that one just like the following.
wa_all_ok = wa_stars.
than do your processing on that wa_all_ok instead of wa_stars
Please Reply if any Confusion,
