Reg: Use of Sales order BAPI (Simultaneously in various batch jobs)

Hi,

I have to run Sales Order BAPI to update various orders. I have checked that updating 500 order lines is taking Approx. 1hr.

My question is if I run various jobs simultaneously(using this BAPI, 500 order lines at a time) in background, then will this affect the time for the completion of each job. i.e. each job updating 500 order lines will still take 1 Hr or there will be some extra delay in it.

I have to Update nearly 25,000 order lines.

Thanks and regards,

Pankaj Bist.
