CP manufacturers need to validate that the conditions for the contract have been met in order to release the off-invoice price on the purchase order or to accept or chargeback the claim/deduction to the distributor as an invalid settlement once the back-up detail has been obtained and reviewed. The validation task is administrative and usually performed by an entry level/low paying position.  

The validation process requires the review and validation of a large amount of volume purchased and comparison with purchase orders. In the case of a settlement, you must validate that the conditions have been met using the claim backup detail.
