How can i use index in select query.. facing problem with the select query.
I am facing a serious problem in one of the select query. It is taking a lot of time to fetch data in Production Scenario.
Here is the query:
SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
FROM ztftelat LEFT JOIN ztfzberep
ON ztfzberep~gjahr = st_input-gjahr
AND ztfzberep~poper = st_input-poper
AND ztfzberepcntr = ztftelatrprctr
WHERE rldnr = c_telstra_accounting
AND rrcty = c_actual
AND rvers = c_ver_001
AND rbukrs = st_input-bukrs
AND racct = st_input-saknr
AND ryear = st_input-gjahr
And rzzlstar in r_lstar
AND rpmax = c_max_period.
There are 5 indices present for Table ZTFTELAT.
Indices of ZTFTELAT:
0 Primary key( RCLNT,RLDNR,RRCTY,RVERS,RYEAR,ROBJNR,SOBJNR,RTCUR,RUNIT,DRCRK,RPMAX)
005 Profit (RCLNT,RPRCTR)
1 Ledger, company code, account (RLDNR,RBUKRS, RACCT)
2 Ledger, company code, cost center (RLDNR, RBUKRS,RCNTR)
3 Account, cost center (RACCT,RCNTR)
Z01 Activity Type, Account (RZZLSTAR,RACCT)
Z02 RYEAR-RBUKRS- RZZZBER-RLDNR
Can anyone help me out why it is taking so much time and how we can reduce it ? and also tell me if I want to use index number 1 then how can I use?
Thanks in advance.
