STRUCTURE OF PROGRAMS THAT USE PARALLEL PROCESSING

I WANT THE STRUCTURAL PROGRAM FOR PARALLEL PROCESSING.

DON'T GIVE THE LINKS.

TRY TO EXPLAIN IN CLEAR VIEW, SO THAT POINTS WILL BE REWARDED.

Hi Arun,

Generaly we are not using loop in a loop for performance issue.

But sometimes we have to follow this for catering requirement.

That time when you are using 2nd loop, add a where clause for giving condition. (condition value is coming from 1st internal table).

Loop at int_tab1 into wa_tab1.

Loop at int_tab2 into wa_tab2 where matnr = wa_tab1-matnr.

endloop.

This tecnique is called Parallel cursor.

Hope it will suffice the requirement.

Regards

Krishnendu

hai,

Parallel processing is implemented in ABAP reports and programs, not in the background processing system itself. That means that jobs are only processed in parallel if the report that runs in a job step is programmed for parallel processing. Such reports can also process in parallel if they are started interactively.

Parallel-processing is implemented with a special variant of asynchonous RFC. Itu2019s important that you use only the correct variant for your own parallel processing applications: the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword. Using other variants of asynchronous RFC circumvents the built-in safeguards in the correct keyword, and can bring your system to its knees

hi guys,

I just want the structure of parallel processing.
