Additional Process Information 
When specifying multiple account assignment for an item, you must consider the following points:
The costs can be allocated on a quantity or percentage basis (for example, 10 pieces or 10% of the order value to cost center 100).
In this case, the accounts are charged with the invoiced amount of the partial delivery. For each purchase order item with multiple account assignments, you can specify whether the cost allocation is carried out proportionally or on a progressive fill-up basis.
