Weyerhaeuser has defined organizational structures for asset accounting in SAP, including two charts of depreciation (W0US for USA and W0CA for Canada) to meet financial and legal requirements. Company codes have been created and assigned to the appropriate chart of depreciation based on their country. Account determinations and general ledger account assignments have been configured to allow for proper asset accounting and valuation transactions to be posted to the general ledger. Screen layouts and asset classes have also been defined to organize asset master records and assign default attributes.
