Maintain Charges Category PCS. not working.

Hi Everyone,

After I post P.O., Product Receipt and Vendor Invoice. I tried to process under Purchase Order > Purchase tab > Manages Charges > Category > PCS not working they have warning…" Charges per unit are not allowed " is they have any possible way to process that transaction…

Scenario: Client want to process handling fee, Costume Duty Charges and other charges after they posted the Vendor Invoice and they want to add that cost of charges to Inventory Item cost.

Thanks in advance.
