Parallel cursor and Parallel processing are different concepts.

Hi,

You can trigger multiple background jobs using the multiple background processes that are available. You can check the number of background processes available in SM50.

Also this is subject to the fact that the basic range of selection can process the data in parallel. i.e. facts like they access same tables for update or same entries in a particular table.

Some design level considerations have to be done like what is the range like say employee numbers or document numbers are generated after processing then not advisable not to as you can end up using same number ranges an thus may pick wrong document numbers or end up waiting for access.
