Example: Distributing Unplanned Delivery Costs 
In Customizing for Invoice Verification, you configure how the system should distribute unplanned delivery costs among the invoice items.
Unplanned delivery costs are distributed among the invoice items in proportion to the total invoiced values in the current invoice, for example, as follows:

This results in the system distributing the unplanned delivery costs as follows:
1. First invoice item at time of first goods receipt = $1000
First invoice item at time of second goods receipt = $1000
Total: $2000
2. Second invoice item at time of second goods receipt = $500
Total: $500
3. This gives a ratio of 2000 : 500 = 4 : 1
The unplanned delivery costs of $100 are distributed in the ratio of 4:1 among the invoice items for materials A and B:
$80 of the delivery costs are allocated to material A.
$20 of the delivery costs are allocated to material B.
