Accounts are history-keeping, like the parties above: each version carries the account's code, name, class, its place in the account-group structure, and whether it is a control or contra account — so a ledger figure sliced by account group reflects the chart as it stood when the entry was posted.
Branches, departments and warehouses show current values only. They answer "where is this now, and under which roof does it sit?" — questions about the present shape of the business — so a single current version of each is kept, and renaming a branch renames it everywhere it appears. Where these dimensions are switched off for your company (0.6), they simply do not appear as slices.
