Parallelization of 0CO_OM_NWA_2 extractor

Each week, I load labor cost data from this extractor to my Cost Cube. Each week, I pull 2 million rows. Each week, I have to wait for 5 hours before the extractor starts to pull data. Then, BW processes the data very efficiently, under 90 minutes. I've read most of the notes I can find regarding the performance of this extractor and have implemented most of the changes.

My question is: Can I establish separate initializations for this extractor, each with a range of Network Activities, and then use parallel extractors (one for each initialization range) to pull and process the data faster?

For that matter, can I apply the same approach to my CCA_9 extractor?

Regards,

George.
