Problem for Accessing the Table BDCP..CDPOS..CDHDR..

Former Member — Thu, 03 May 2007 10:36:43 GMT

Hi Guys,

i have the problem of accessing the BDCP table.it is working fine in development and testing server.it is taking more time in background in Production server..can anyone help me to optimize this code and please suggest me if i can change anyof the below logic..

Thanks a lot in advance.

LOOP AT t_cdobjid.

objectid-low = t_cdobjid-cdobjid.

objectid-sign = 'I'.

objectid-option = 'EQ' .

APPEND objectid.

IF count = 50.

CLEAR count.

SELECT * FROM bdcp APPENDING TABLE t_bdcp

tabname = 'DMEAN' AND

fldname = 'KEY' AND

cdobjid IN objectid.

CLEAR : objectid.

REFRESH: objectid.

ENDIF.

ENDLOOP.

IF NOT objectid[] IS INITIAL.

SELECT * FROM bdcp APPENDING TABLE t_bdcp

WHERE cretime IN r_cretime AND

tabname = 'DMEAN' AND

fldname = 'KEY' AND

cdobjid IN objectid.

Hi Prabhu!

Just define your own change pointer (WE81) and assign only the fields (BD52) you are interested in. (Don't forget to activate the message (BD50). Then you only get change pointers for DMEAN / KEY and MARA / EAN11 and you can use the standard FM CHANGE_POINTERS_READ for reading and CHANGE_POINTERS_STATUS_WRITE for setting the process flag (otherwise you would read the pointers not only once).

Regards,

Christian

Hi,

One way to optimize this code is to move the select queries outside the loop. You can do it by fetching the data in an internal table n then use FOR ALL ENTRIES in SELECT query.

Its taking more time in production because you might have large data in production.

Use the PACKAGE SIZE oprion of the SELECT statement:


LOOP AT t_cdobjid.

  objectid-low = t_cdobjid-cdobjid.
  objectid-sign = 'I'.
  objectid-option = 'EQ' .

  APPEND objectid.
  CLEAR objectid.

ENDLOOP.

SELECT * FROM bdcp APPENDING TABLE t_bdcp
  PACKAGE SIZE 5000
  WHERE cretime IN r_cretim AND
        tabname = 'DMEAN'   AND
        fldname = 'KEY'     AND
        cdobjid IN objectid.

ENDSELECT.

IF NOT objectid[] IS INITIAL.
