Landed Cost Voucher, Purchase Receipt and Incoming Value

Hello

We have a situation where our employee put the price of an item $ 1575 instead of 15.75 in Purchase Order by mistake and submitted and received the Stock ( PREC ) which has Batch numbers. Now when we tried to Create a Landed Cost Voucher, we realized this mistake. Now its not allowing us cancel because stock is sold, not able to change price because its already submitted. How do we handle this situation. Incoming Value is showing based on price on the PO.

Also:

We don’t know prices when we create PO and PREC and system is taking and calculating Incoming Value only item price from Purchase Order. We do have to change prices even after Receiving when we create PINV since we handle shipments on consignment.

Please give us a suggestion how to handle this, We really appreciate and Thanks in Advance
