In Trade Allowance Management, a Trade Allowance (Trade Promotion) can include a lump sum activity where we agree to pay our customer a sum of money for doing something for us, such as advertising our product on their website.  Currently, this functionality is greatly limited by the fact that I can only set up 1 expense account for all trade allowances that include a lump sum, regardless of item, customer, date range or promotion.  This Expense account is set up on the Trade allowance management parameters.  Businesses require the ability to vary that Expense account for different trade allowances/lump sum promotions.  Ideally, similar to how Rebate Program Ids allow us to setup flexible expense and accrual accounts, lump sum promotions desperately needs the same capability.  Lack of this core capability often steers businesses away from using AX/D365 for this functionality or requires this customization for every implementation.
