Invoice Setting - Coupon Application Order

• A value of LIFO (default), will result in a coupon to be applied to an invoice based on Last-In-First-Out coupon assignment order.
• A value of FIFO, will result in a coupon to be applied to an invoice based on First-In-First-Out coupon assignment order.

• When there are different levels of coupon applications (e.g., MPI and account), the MPI coupon assignment order will take precedence over account coupon assignment order.
• A more granular setting of coupon application order (e.g., coupon groups) will take precedence when in conflict with this parameter. 
• When a group of coupons are assigned within the same second, the order of application will be in the order that Oracle pulls them.

• A consistent manner of applying coupons (e.g., from the same level) should be employed that works in conjunction with this parameter setting for the most predictable processing results. 
• The parameter is editable, but best practice is to not change the parameter frequently. The change will be reflected on the next invoice (not going retroactive).
