It is possible that costs estimated for a contract or commitment might decrease or increase during the contract operations. This kind of increase or decrease in estimated costs might occur at any stage of the commitment process. In order to track such changes historically, Estimated Costs option is used.
Estimated Costs option is located under the Attached Records menu of Transactions > Sales Contracts.
Any increase or decrease in estimated costs will inevitably affect the total contract amount. Accordingly, advance and progress payment calculations are performed over the contract amount after the estimation.
