First i updated product cost price.

After validating incoming shipment, value updating in the product cost price is right.

But after posting landed cost, value updating in the product cost price is wrong.

ie, Product cost price = 150.

Then i changed the product cost price to,

Product cost price = 200.

so the difference amount = 50.

After validating landed cost, it subtracts the difference amount from the landed cost value and updating in the product cost price.

Actually i dont need to subtract this difference amount from landed cost. I want to update, whatever value i got from the landed cost as the product's cost price.

for eg: if i got landed cost = 300. after validating it subtracts 300-50 = 250. and updates 250 as product cost price.

I want to update 300 as product's cost price.

How to solve the solution? Please help me.
