You can generate price difference invoices for the assets that are not linked to any material over Asset Purchase / Asset Sales Invoices browser.
To do so, click Apply Price Difference option in the right click menu of the Asset Purchase / Asset Sales Invoices browser. Organizational Unit, Department, AR/AP and Trading Group etc. information and invoice lines are transferred to the corresponding fields of the price difference invoice and invoices are linked.
When attempted to establish a link to the asset purchase / sales invoice over price difference invoice, an asset category (real estate, equipment, transport vehicle or other asset) is selected in line and asset purchase / sales invoices are listed in "Invoice Connection" field depending on the selected category. When line type is one of the asset categories, and you want to continue with Transfer Invoice option that is under the Operations menu, you select from the existing asset sales/purchase invoices.

Price differences also affect asset input cost and depreciation calculations. Price differences which incur for asset purchase and sales invoices are reflected to the Total Price Difference field in asset definition fixed asset record. While calculating asset depreciation, start cost is updated considering the price difference amount. If there are other lines which are calculated and posted to General Ledger, depreciation difference is added to the next period.
