Is AP/AR Netting possible when the calculation point for withholding is either Payment or Both

I completed all the configuration on AP/AR Netting and when i run the Netting settlement, the log says

"The invoices for the Business Unit are excluded because the calculation point for withholding is either Payment or Both."

Please confirm, if Netting is possible, when the calculation point for withholding is either payment or Both.

Thank you
