MESSAGE class problem.

Question

Hi ,
I have coded an error message for my form by using below syntax.
MESSAGE ID 'Z0' TYPE 'E' NUMBER '999' WITH 'Please maintain cust pricing grp 34 for' wa_zmas-matnr .
It worked fine when i try to display the form with an error message in tcod : vf03
Then i try to cancel this billing document in tcode : vf11 and able to save without a problem.
Now my problem is, when i try to view this billing document again via tcode : vf03 again, there's is an error message shown by the system :
Express document "Update was terminated" received from author "ABCDE".
This indicates that my cancellation/reverse of this billing doc no its not successful.
I was wondering is it cause by my above code but when i try to do the cancelation, it did not went through my coding? Please help.
Thank you.

Hi, below its my coding (bold).
-i suspected its the error message. This is because once i uncomment the message class, the error will not appear.
-i have problem in create billing too.
-my process was, i create a new billing --> click on save button --> view my new billing via vf03  --> pop up error msg.
-pop up error message : Express document "Update was terminated" received from author "USER01".
-when i check my inbox msg, it shown below.
  Update was terminated
  System ID....   DEV
  Client.......   300
  User.....   DCABAP03
  Transaction..   VF01
  Update key...   16AE88DE0111F11EA300001A64635E5E
  Generated....   14.08.2009, 16:40:21
  Completed....   14.08.2009, 16:40:22
  Error Info...   Z0 999: Please maintain cust pricing grp 34
- i realised that the error info it's the same with my coding.
- my main purpose its to display this error message once i print preview the form via vf03 output type only.
LOOP AT it_zmas INTO wa_zmas.
      IF wa_zmas-mtart = 'FIN' AND wa_zmas-fkimg NE '0'.
        LOOP AT tvbdpr WHERE posnr = wa_zmas-posnr AND matnr = wa_zmas-matnr.
*read internal table it_zmas to save uecha, gross value and discount.
          READ TABLE it_zmas WITH KEY posnr = wa_zmas-posnr matnr = wa_zmas-matnr.
          IF sy-subrc = 0.
*to retrieve uecha from tvbdpr and to compared with intab-posnr. intab posnr its taken from tvbdpr-uecha and tvbdpr-posnr.
            IF tvbdpr-uecha <> 0.
              it_zmas-uecha = tvbdpr-uecha.
            ELSE.
              it_zmas-uecha = tvbdpr-posnr.
            ENDIF.
*to retieve cust pricing group and material table.
            SELECT SINGLE knumh INTO zknumh FROM a960

              AND matnr = wa_zmas-matnr
              AND datab LE tvbdpr-prsdt
              AND datbi GE tvbdpr-prsdt.
*if there is cust pricing grp available continue else display error message.
            IF zknumh IS NOT INITIAL.
              SELECT SINGLE kbetr INTO (zkbetr) FROM konp
                WHERE knumh = zknumh.
*determine gross value
              it_zmas-gross_value = zkbetr * wa_zmas-fklmg.
              LOOP AT intab WHERE matnr = wa_zmas-matnr AND posnr = it_zmas-uecha.
                AT NEW posnr.
                  SUM.
                  zkwert = intab-kwert.
                ENDAT.
              ENDLOOP.
*determine discount
              it_zmas-discount = it_zmas-gross_value - zkwert.
              MODIFY it_zmas.
            ELSE.
         *MESSAGE ID 'Z0' TYPE 'I' NUMBER '999' WITH 'Please maintain cust pricing grp 34'.*
            ENDIF.
            CLEAR zknumh.
          ENDIF.
        ENDLOOP.
      ENDIF.
    ENDLOOP.
