Hi, 

I am new to Microsoft Nav 2015. Could you please advise me on an issue I am having.
We have several closed RPOs'. It is now in archives. We do FIFO inventory valuation method. When the RPO was open adjustment had been made and these values had taken inventory at a different value than the original value (as it happens in FIFO method)My questions are-
1)How did the RPO close when the net is not zero after output was recorded? ( the differences in per unit RM valuation * qty) After all, this means there is a WIP balance still in that RPO
2) Where did this balance end up on the Balance sheet and P & L?
3) How do I correct the problem?

4) How to prevent this in the future?
