Actual Cost not getting updated in Sales Document

Dear all,

We have a scenario wherein in MTO sales, customer gives an order. Cost estimate is done and calculated costs (Planned Costs) gets updated in EK02 condition type in sales order. After the product is ready down the line over six months, costs are again calculated (Actual Costs), but in the sales document, this Actual Costs is again not getting updated.

Kindly suggest how to go about this.

Thanks and Regards
