 The Contracted Unit Price represents the agreed-upon unit price for a single [Pricing Unit](#pricingunit) of the associated SKU, inclusive of [*negotiated discounts*](#glossary:negotiated-discount), if present, while excluding negotiated [*commitment discounts*](#glossary:commitment-discount) or any other discounts. This price is denominated in the [Billing Currency](#billingcurrency). The Contracted Unit Price is commonly used for calculating savings based on negotiation activities. If negotiated discounts are not applicable, the Contracted Unit Price defaults to the [List Unit Price](#listunitprice).
 
-The ContractedUnitPrice column MUST be present in a [*FOCUS dataset*](#glossary:FOCUS-dataset) when the provider supports negotiated pricing concepts. This column MUST be a Decimal within the range of non-negative decimal values, MUST conform to [Numeric Format](#numericformat) requirements, and be denominated in the BillingCurrency. It MUST NOT be null when [ChargeClass](#chargeclass) is not "Correction" and [ChargeCategory](#chargecategory) is "Usage" or "Purchase", MUST be null when ChargeCategory is "Tax", and MAY be null for all other combinations of ChargeClass and ChargeCategory. When ContractedUnitPrice is present and not null, multiplying ContractedUnitPrice by [PricingQuantity](#pricingquantity) MUST equal [ContractedCost](#contractedcost), except in cases of ChargeClass "Correction", which may address PricingQuantity or any cost discrepancies independently.
