Process Multiple Change Order at same time (PIM Change Order by API Parallely)

Hi,

we are creating Change Orders by API.

We are Creating Change Order for each time. (20000 eaCH DAY).

the Change Order program is incomparable to itself.

so it is getting queued.

So it is taking a huge time to complete all the change Orders.

So how it is possible to process the change Orders parallely or any other way ...so that it will complete in faster way.

(donot want to create One change Order for all item)

Thanks,

Lingaraj
