How to use Parallal Processing

Former Member — Fri, 23 May 2008 10:15:43 GMT

Hi All,

How to use Parallal processing in our report program, My report has to execute by forground. i have checked this bwlow link, they mentioned some small code here. but how to use and where to place this code in my report program.

http://help.sap.com/saphelp_nw70/helpdata/en/fa/096e92543b11d1898e0000e8322d00/content.htm

Thanks,

Subbu.

That link gives you all the information you need, including a fully annotated sample program. What more information do you want?

Hi Matthew ,

Thanks for your reply.

I have a one report, it will generate output list with interactive way. This is normal report contains 2000 lines. How to implement this parallal process in my report.

I could get how to use this process with the link information.

If you dont mind explain with small a program.

data kna1 like kna1 occurs 0 with header line.

select * from kna1 into table kna1.

data var type i.

loop at kna1.

var = var + 1.

write:/ kna1-kunnr.

if var = 1000.

exit.

endif.

endloop.

This is my sample program how to use this process in this program.

Thanks,

Subbu.

Your sample program is not really suitable for parallel processing. You need something that can be split into two or more independent processes.

In addition, the runtime of the overall process should be so critical that it warrants the extra effort and added complexity of the parallel approach.

Cheers

Ok...

Below is the some part of the program...If it possible to insert the parallal processing please let me know...It very urgent for me....

LOOP AT ITAB.

PERFORM MOVE_GR_AMTS_TO_ITAB.

exit.

endif.

ENDIF.

ITAB-IR_VALUE_DOC = ITAB-IR_VALUE_DOC + ekbe-WRBTR.

ITAB-IR_VALUE_LOC = ITAB-IR_VALUE_LOC + ekbe-MBTR.

IF ITAB-CURR_PO = ITAB-CURR_CO.

ITAB-IR_VALUE_CO = ITAB-IR_VALUE_CO + ekbe-WRBTR.

ELSE.

PERFORM GET_CURR_RATE USING ekbe-WAERS ekbe-BUDAT CHANGING GS_RATE.

endloop.

ENDFORM.

Hi ,

Get the basic requirement of using the PArallel processing.

You can use the parallel processing with only Function modules(RFC only).

You can call this fm's in parallel processing, inside a loop.

Now for your case, if you want to improve the performance of your program by implementing the Parallel processing, first get the logic moved inside a FM(rfc) and then use the fm like below

CALL FUNCTION 'XXXX'

IN NEW TASK <task name>

DESTINATION <destination name>.......

I hope you have seen the help , if still u have some doubts in using this plz post again, may be i will try to clear you
