I know where BW Statistics are used and I know how to install the BW Statistics in BW. But
1. People say that we need to load the data into statistics cubes using infopackages. But what data we need to load and from where do we need to load?
2. Do we need to keep on loading the data for ever?
3. How does the data loaded is useful in improving the performance of the BW System(loading/Queries etc..)?
