Condition type for pricing came from PC but has not included the additive cost record

hello all;

we have the pricing base for the sales order with the estimated cost from pc; our costing process has a posting record for additive cost is not included on the total cost is sent to the condition type EK02.

question: It is possible to include these kind of postings?, in fact, these record apear on the costing report as part of the cost of sales..

thanks in advanced...
