Hi everyone.

I have the following problem:

One Purchase order with 2 invoices in foreign currency on different dates, and exchange rates. This is a Project PO, so all the items immediately are "sold" to project.

Purchase price is 1 in EUR. 

First invoice posted on correct price 0,78 in GBP.

Second invoice had to be posted on 0.74, instead it posted on 0,76.

My next Closing and adjustment process adjusted the first invoice price to 0,76.

SO now, I have two wrong prices, that were corrected, obviously, on average purchase price of this particular PO.

In the same time I can see that in InventTrans Purchases were correct, but the transactions to Project were accordingly with price 0,76.

Can someone help me out to understand what parameter is causing this issue? 

Thanks in advance
