Hi Kate,
please post the whole execution plan in DBMS_XPLAN output (can be done via ST05 in text mode as well) and the corresponding table and index definition of table "/BIC/AZA_32S00" (DBMS_METADATA via SE14).
You are already using partition pruning (only partition 10 is accessed) so it is important to know the exact structure (e.g. partition key, index definition, etc.).
Regards
Stefan
