BAdI to overwrite EVC and NPV formula in portfolio element

Hello guys,

is there any possibilty to overwrite the the calucaltion formula for the ECV and NPV value for the portfolio elements?

Financial Information About Items and Initiatives - SAP Portfolio and Project Management - SAP Library

We don't want to use the probability of commercial success and the probability of technical success. We'll use a much simpler calculation.

Does somebody know if there are any BAdI's or User Exits to do so or can at least one tell me where the calcution is done (function module, oo class, etc.).

Is there any opportunity to make self defined keyfigures from the XRPM_KFM_ADMIN avialable in the BCV dashboards?

Thank you very much for your help.

Kind regards

Fabian
