[Axapta-Knowledge-Village] HRM Ax 40 vs 2009

[Axapta-Knowledge-Village] Storage dimension

There are 5 storage dimensions under dimension groups (Warehouse, batch number, location, pallet id and serial number) Is there anyone who has expaned this with one or more dimension(s) e.g. date? What is the proper way to do this? Is there any description out there? Regards Fredrik ---
