Allocation rules enable coordinating style items.

For example, coordinates such as jackets and trousers are delivered at the same time. Other coordinates can be sold separately, too. You use top and bottom management functionality to coordinate style items that you deliver at the same time.   

The system applies specific processing for every order if the Top/Bottom Management (Y/N) processing option on the Top/Bottom Processing tab of the Generate Allocation and Delivery Proposals program (RCW06) is set to Y.
