In our project there is requirement of result analysis based on percentage of completion (POC method). The method used for POC calculation is cost proportional method.
In our case the cost planning is done at the top level WBS manually whereas the below level networks also have cost which appear automatically due to the BOM transfer and it is restricted upto the network with the help of apportioned order.
As per the calculation POC should be actual cost / planned cost.
Desired result is that the planned cost should be the cost which is manually entered at the 1 st level WBS . But the issue is while doing CNE5 the planned cost is taken as the planned cost occure automatically due to the network costing.
Kindly provide the solution.
