This change lets companies manage multiple operating units and assign them to key business documents such as invoices, sales orders, purchase orders, point-of-sale orders, payments, expenses, and journal entries. When enabled, reports and document headers can show the relevant operating unit's details instead of only the parent company, improving accuracy for multi-branch or multi-division operations.
