Code Optimization

Former Member — Sat, 04 Sep 2010 09:25:34 GMT

Hi Master's,

Can any one please guide me?

How to optimize the following code,

v_cond = 'MWST'.
perform seg_value using v_cond.
v_cond = 'ZAO1'.
perform seg_value using v_cond.
v_cond = 'ZAO2'.
perform seg_value using v_cond.
v_cond = 'ZAD3'.
perform seg_value using v_cond.
v_cond = 'ZADD'.
perform seg_value using v_cond.
.
.
. It goes like this....

Form seg_value using v_cond_type.
CLEAR: v_frt,int_edidd, int_z1eds02.
  LOOP AT i_cond WHERE  kschl = v_cond_type.
    v_frt = v_frt + i_cond-kwert.
  ENDLOOP.
  CASE l_tcurx.
    WHEN 0.
      int_z1eds02-summe = v_frt * 100.
    WHEN 1.
      int_z1eds02-summe = v_frt * 10.
    WHEN 2.
      int_z1eds02-summe = v_frt.
    WHEN 3.
      int_z1eds02-summe = v_frt / 10.
    WHEN 4.
      int_z1eds02-summe = v_frt / 100.
    WHEN 5.
      int_z1eds02-summe = v_frt / 1000.
  ENDCASE.
  SELECT SINGLE * FROM t685t WHERE spras = 'E' AND kschl = v_cond_type.
  int_z1eds02-kotxt = t685t-vtext.
  CONDENSE int_z1eds02-summe NO-GAPS.
  int_z1eds02-sumid = v_cond_type.
  int_edidd-segnam = 'Z1EDS02'.
  int_edidd-sdata = int_z1eds02.
  IF v_frt <> 0.
    APPEND int_edidd.
  ENDIF.
endform.

Optimize in what respect, apart from adding code tags (now done)?

why do you want to optimize? Is it slow? How slow?

Hi,


 LOOP AT i_cond WHERE  kschl = v_cond_type.
    v_frt = v_frt + i_cond-kwert.
  ENDLOOP.

Define i_cond table as sorted table with non-unique key kschl.


  SELECT SINGLE * FROM t685t WHERE spras = 'E' AND kschl = v_cond_type.
  int_z1eds02-kotxt = t685t-vtext.

You can make changes as follows


Define it_t685t as hashed table with unique key kschl.
clear wa_int_t685t.
Read table it_t685t into wa_t685t with table key kschl = v_cond_type.
if sy-subrc ne 0.
  SELECT SINGLE kschl  vtext into wa_t685t
 FROM t685t WHERE spras = 'E' AND kschl = v_cond_type.
 insert wa_t685t into table it_t685t.
endif
int_z1eds02-kotxt = t685t-vtext

@Ravishankar,

please ask before you recommend something which might be wrong!!!

LOOP AT i_cond

i_cond is probably very small, no optimization necessary

t685t is a buffered table, there is no hashed table copy necessary, the SELOECT SINGLE is fine !!!

I would that there is not performance problem at all, the code was only found be some useless code inspection!

So please analyse before you want to change
