Query failing

Question

Hi,
zzflame_agrt_no & bukrs_vf   are non-primary fields in the table VBAK.
    select  vbeln
              auart
              vkorg
              zzflame_agrt_no
              bukrs_vf
        from  vbak
        up to 1 rows
      into wal_vbeln
      where zzflame_agrt_no = '1212121'
      and   bukrs_vf        = ' DE'.
This query is dying. To improve the performance I created a secondary index in the table VBAK which already has 8 indexes and when I created the index it says "Index does not exist in database system ORACLE ".
I selected non-unique index( Index on all DB systems).
1. How do i remove this message "Index does not exist in database system ORACLE "?
2. My query is for just 1 row but is failing. How do i get the query working ?
Thanks

Hi,
The where clause has non-key fields , thats why i have used up to 1 rows.
Anyways I have tried removing Upto 1 rows & select single also,but its not working... It is because of the non-key fields!!!.
Now tell me how to use non-key fields in where clause of a select query which is also a Zfield in a heavy table like VBAK.
Which is why i created secondary index in the table VBAK...pls refer my original Qn.
Thanks
