..check out "SAP Best Practices" in the SAP HelpPortal. Go to http://help.sap.com, select "SAP Best Practices", expand the "Baseline Packages" branch. These packages include a lot of information on all kinds of business processes. Select a country/language package you need to open the content. This is related to SAO Business Suite.
If you need specific details reg. Busines ByDesign then you need access to the Business Center (http://sme.sap.com). This gives you access to similar, ByD-specific documents and access to self-enablement systems.
I hope this helps.
