Ability to define customer credit limit by dimension. 

example: its common to have a shared customer account with multiple business units or who buys different item categories from the same company. 

for some products that are fast moving a company would want to set 1000 USD, N30 for customer X while for products that require longer time to sell the company would want to set the customer X terms to 10000 USD limit and N120. 

A company i am implementing D365 ops for have hospitals who are sold pharmaceuticals (fast moving) and would require shorter payment terms and less credit limit rather when selling them medical devices.
