Use this tab to specify if, and so which items, must be grouped when creating invoice recommendations. You could specify, for example, whether machine hours may be added up by employee or department, or you could specify that all machine hours may be added up. This means that when grouping invoice data, you can use other settings than when grouping data from the actual costing process. Data grouping for invoices does not affect the pricing.
Select the Cumulate in full check box to add up all costs on an invoice recommendation.
