FP增加的索引

1、优化FP_BOM中第839行执行过慢问题，且会出现ORA-01652: 无法通过 128 (在表空间 STGTEMP 中) 扩展 temp 段ORA-06512: 在 "STG.FP_BOM", line 839
检查发现MST_BOMCOMPONENTS表中BOMID中没有空格，可以却除，另外增加索引

SELECT DISTINCT AM.SCENARIO_ID,
                    AM.ENGINE_ID,
                    AM.ENTERPRISE,
                    AM.SITEID,
                    AM.PROPERTY,
                    CASE WHEN IC.OLD_ITEM_ID=AM.ITEM THEN IC.NEW_ITEM_ID
                    ELSE AM.ITEM
                    END AS ITEM,
