Dimension (of a register)
Each register dimension represents anaccounting slice. For example, a register that stores the item quantities in warehouses can have "Item" and "Warehouse" dimensions. This allows retrieving the quantities of different items in a single warehouse (the "Warehouse" slice"), the quantities of a specific item in different warehouses (the "Item" slice), or the quantity of specific item in a specific warehouses (both accounting slices are applied).
