Hi nakul,
Ok.
The main issue seems to be the price difference that you have between the role based price and the resource based price.
Let's make an example to get things clear.
You have a role based price of $150 for an architect.
There are 3 architects (Nakul, Ludwig, Mr.X).
If Nakul has a cost price of $150,
Ludwig a cost price of $140 and
Mr.X a cost price of $160
Now, if you assign either Ludwig or Mr.X to the WBS task later on, you will see the variance you referred to.
That's ok in my opinion and actually what I would expect to see.
If you don't like this can't you simply use role based prices and forget about those resource specific ones?
Best regards,
Ludwig
