Issue
The PO Header / Line charges does not have any calculations.
Resolution
There are no values in the costing elements were those items meet the criteria to have a costing markup added, currently you have no Markup for Delivery Method = AVC.
Example
PO 200757 / Item 110004501C9201
Costing Elements and Cost distribution key (attribute)
Example E00006 Inbound Freight
Dmt = AVC, Ctr = CN, Item grp = 11101010
No value setup for those criteria to add a markup
