Hi all,

This is my code . is there any other ways to improve performance of this code?

These two select statements are inside a loop,

SELECT * FROM CDPOS INTO TABLE T_CDPOS WHERE OBJECTCLAS ='MATERIAL'

AND OBJECTID = T_ZWPBPH-PBPINO AND FNAME = 'SPART'.

IF SY-SUBRC = 0.

DESCRIBE TABLE T_CDPOS LINES V_COUNT.

READ TABLE T_CDPOS INDEX V_COUNT.

SELECT SINGLE * FROM CDHDR INTO T_CDHDR WHERE OBJECTCLAS ='MATERIAL'

AND OBJECTID = T_CDPOS-OBJECTID AND CHANGENR = T_CDPOS-CHANGENR.

IF SY-SUBRC = 0.

MOVE-CORRESPONDING T_CDHDR TO T_ALV.

If they are outside the loop it will boost the performance.

hi,

1. Before for all entries statement of all the select statements check whether the table has any value or not i.,e if not t_ekbe[] is initial.

2. Avoid using select statements within a loop .

There is a secondary index for BDCP on CRETIME and CDOBJCL so, so long as your range on CRETIME is not empty and mot too large, you should be OK there.

Rob

Former Member · ‎2006 Dec 07

The Table BDCP select is causing the performance issue , as you are not passing the primary key field.

insted you can use the Functional modules for reading the change pointers.

Try FM : CHANGE_POINTERS_READ.

Hope this will be helpful !!

Thanks,
