We are using ARM and commonly have sales orders with quantity = 4 and quarterly billing schedules (4 invoices billed an even amount every quarter - Jan 1, April 1, July 1, October 1).

Every so often, we have a scenario where one of the invoices is incorrect (wrong memo, a duplicate was mistakenly created, etc) so we create a credit memo w/ qty = 1 and apply it to the invoice. However, this creates an issue for us where revenue is under-recognized by 1 unit.

• Since this process results in 5 invoices being created, all 5 invoices are put into Deferred Revenue.
• The original SO created has quantity = 4 and (fulfilled quantity = 5) invoices and creates a Revenue Arrangement worth 4.
