For base metal concentrates, it is common for contract charges or payable analyte charges (in particular, refining and treatment charges) to be based on the price of a payable analyte. In some cases, the pricing rules for a charge require different calculations than those used for the payable analyte on which it is based. Scale pricing (or 'payable analyte scale pricing') can be used to define pricing rules for the charge.
Scale pricing can be defined only if the charge is entered as a Tiered value, the Tier Concept is Payable Analyte Scale Price, and a Tier Analyte is selected.
