Key points

  • Statistical Accounts store non-financial metrics like square footage that drive cost allocation calculations
  • Allocation Accounts use Statistical Account data to automatically distribute costs across selected dimensions
  • When posting purchase invoices to an Allocation Account, the system proportionally splits amounts based on dimension values stored in the Statistical Account
  • Updating the Statistical Account journal automatically applies new allocation proportions to future transactions without reconfiguring the Allocation Account
