Difference in planned cost, reported cost and actual cost.

Looking at one of my projects there differences between values being returned on the project transaction view and the project navigator view.

We’re only talking a few pounds in this example however it doesn’t make sense and it would be good to know why these differences are there.

The difference in planned cost versus reported cost is pence and could be attributed to rounding differences (which in itself is frustrating) however its the total actual cost from project transactions versus total actual cost from the project activity which is causing the confusion

Anyone seen this before or know where the values are coming from ?

Thanks in advance
