Invoicing special services

Special service with associated product lines is invoiced based on product and special service association.

The invoiced quantity on the special service lines is computed based on how much product quantity is invoiced. For example, the product quantity and the special service line quantity maintain a ratio of 1:2, respectively. if the product quantity is 10 and the special service order line quantity is 20, the product is invoiced for 2 then 4 quantity of special service is invoiced.

Order Line Option Quantity and Price Calculation for Special Services
Order Line Option Qty = Order Line Qty * (No. of associated special services per product item)
Order Line Option Price = Order Line Option Qty * Order Line Option Unit Price

Whenever an order line option is invoiced, it is assumed that the option price does not change post the first invoice. For service or delivery lines this does not change. For product lines that have special service item as an option, the price change post invoice is handled based on the value of the APPLY_PRICE_CHANGE_TO_INVOICED_QTY pricing rule. For example, consider the following scenarios. In both the scenarios consider this the catalog configuration. Product item Prod1 and Special Service SS1. 2 qty of SS1 is associated with Prod1. Unit Price of Prod1 is $0 and Unit Price of SS1 is $10

Case 1: when APPLY_PRICE_CHANGE_TO_INVOICED_QTY = N

When an order line option unit price is changed, the new unit price is applicable only to uninvoiced option quantities. If an order line is completely invoiced, change to order line option unit price displays an error unless the line quantity is increased.

Case 2: when APPLY_PRICE_CHANGE_TO_INVOICED_QTY = Y

When Order line option unit price is changed, new unit price is applicable to all the order line option quatities. For already invoiced order line option quantities, an adjustment invoice is created. If the order line option unit price is increased, an adjustment invoice of type DEBIT MEMO is created and if the order line option unit price is decreased, an adjustment invoice of type CREDIT MEMO is created.
