Trade allowance management is a great module to use for trade promotion support. It supports off-invoice, billback and lump sum types of discounts. The billback discount in the backend uses the old rebate management functionality. MS has released a new Rebate Management module which provides more features and functions. The TAM module should be updated to allow our customers to take advance of the new rebate management features. Additionally, most customers in this space have requirements for some rebates that are part of trade promotions and some that are not. Having to use 2 completely different modules to support this requirement is extremely difficult.
