Performance tuning for JCDS query

Question

Hi All,
I have a performance issue in following query.Any Idea how can it be improved?
    SELECT objnr udate utime
           FROM jcds
           INTO TABLE it_jcds
           WHERE objnr LIKE c_or
            AND   stat = l_tj02t
            AND   cdtcode LIKE c_co
            AND  inact = space.
Fields          Distinct values
CDTCODE                  111
INACT             192
Only one index i.e Primary Index
UNIQUE     Index   JCDS~0 (Compute)
Column Name                     #Distinct
MANDT                                          3
OBJNR                                  2.165.245
STAT                                         100
CHGNR                                        319
Is 'like' statement causing the performance issue and how can it be corrected?
Or Index can be created for this?

Answer 1

You can try this: Create 2 ranges, for objnr and cdtcode and fill like:
ra_objnr-sign = 'I'.
ra_objnr-option = 'CP'.
ra_objnr-low = 'OR*'.
append ra_objnr.
ra_code-sign = 'I'.
ra_code-option = 'CP'.
ra_code-low = 'CO*'.
append ra_code.
SELECT objnr udate utime
FROM jcds
INTO TABLE it_jcds
WHERE objnr IN ra_objnr
AND stat = l_tj02t
AND cdtcode IN ra_code
AND inact = space
