Hi Oracle team,

We want to set up 1 more type of SO, so that we can have 2 types of Return SO as below:

Type 1: Return SO (Currently have in system already) - used for actual return SO from customers, which will have Credit memo with sales account is Returns of goods. and when run cost, COGS will be reflected in Returns of goods, instead of reverse COGS. So we can know the amount of returns from customer

Type 2: Reject SO (need to be added). - used for the case we want to cancel SO. Credit memo: sales account is Sales revenue (reverse amount of Original invoice), and COGS account is Cost of goods sold (reverse amount of Original COGS recognition). So we can totally net off the amount should be cancelled.
