Use this tab to define agreement invoice rules that will be applicable to the services included in the service contract. The rule can be applied to either sales groups or cost types. For each agreement invoice rule and connected sales group or cost type, you can specify if corresponding posting lines with a zero invoice amount should be included in or excluded from the customer invoice. Use the Percentage field to denote how much of the sales price (if sales group) or cost (if cost type) you wish to include or exclude from invoicing. Note: a percentage of 100% denotes the total amount of the sales group or cost type.
