AT NEW in loops

Question

Hi everyone
I have an internal sorted table (itab1) which contains data from table VBAP based on a unique key using VBELN and POSNR. I want to extract the first row for each VBELN into a seperate hashed table (itab2) with a key of VBELN.  Two restriction apply:
1. I need to retain the data in POSNR as itab2 will be used to read another internal table later on with a key of VBELN and POSNR
2. I need to keep the contents of itab1 for use later in the program so cannot just do a DELETE ADJACENT...ON VBELN to remove the 'duplicates'.
I have tried the following:
LOOP AT itab1 INTO wa_itab1.
    AT NEW vbeln.
      INSERT wa_itab1 INTO TABLE itab2.
    ENDAT.
  ENDLOOP.
However, immediately after the AT NEW command has executed the contents of wa_itab1-posnr become '*****'.  My question is therefore, why does it do this and is there a way that I can get the work area to retain the value in POSNR?  Perhaps my logic is flawed - is there a better way of achieving my goal?
Thanks
Andrew

when using AT NEw u have to use read statement
LOOP AT itab1 INTO wa_itab1.
  <b>v-inex = sy-tabix</b>
    AT NEW vbeln.
   <b>read table itab1 into wa_itab1 index v_index.</b>
      INSERT wa_itab1 INTO TABLE itab2.
    ENDAT.
  ENDLOOP.
