Increase planning performance using BWA?

Hi,

does anybody know if the performance of a planning application using Integrated Planning increases if using BWA? From my point of view the planning buffer for IP and the BWA data are separated.

I only can imagine that the planning buffer is filled out of the BWA with e.g. actuals and data out of closed planning requests. That means that only the reporting part (filling of planning buffer) is speeded up. A decrease of planning application runtime is not achieved.

Is that right?

Thanks for help in advance!
