Problem in Contract - New price not being updated in EKPO table, but displa

Hi

We have a contract(WK type) with two validity periods and prices. The first validity period ends with 31/12/2006 with 1 USD and we have new validity period whcih starts from 01/01/2007 to 31/12/999 with 1.5 USD. In display the contract shows 1.5 USD as the net price. But while printing it printed 1 USD which is the old price. On investigating this issue, we found that the EKPO->NETPR filed contains the old price (1 USD). But in the screen of ME 33K, it shows the new price and by pressing F1 to find the field it shows EKPO->NETPR only. Can anybody help on this, why the new price is not updated in to the EKPO table.

Thanks
