PoC on project planned cost

Hi Experts,

My customer recognizes his revenue based on percentage of completion on projects. The accrual method we are using is 108- Cost-to-Cost POC Project.

With this method, the PoC is calculated on total project planned cost. However, we would like to remove from the total project cost the planned cost of material and other expenses. The standard we are following is that as the revenue gain is mainly from labor, the rules is telling us that the way to calculate the revenue is aligned with the way that is revenue is gained.

Long story short, we need to have this kind of calculation :

Actual Labor / Labor project planned cost ONLY (instead of total project planned cost) = %

Is there a way we could trigger this calculation automatically from ByD ?

Any suggestions ?

Thank you for your attention,

Andréanne
