Items defaults (including Replenishment: automatic drafting and safety days, Chapter 10.8, and Reserve stock when a sales order is confirmed, Chapter 5.6), Item attributes, Warehouses (and their bins), Putaway rules and Units of Measure — Chapter 10, section 10.9. Business units — reporting segments (a region, division or outlet) with Name, Code, Address, City, Country, Phone, Email, Website and a Primary flag; documents and ledger postings carry the unit so reports can be filtered by it. A business unit is not a legal entity: the organisation has one currency, one chart of accounts and one tax registration. A separate legal entity is a company — add one under Settings → Organization → Companies (section 22.1).
