Hi,
In your first step of PMP, have rate valuation for forward exchange transactions. In the forward rate valuation type, specify the forward category as NPV to be picked from risk module and in the MRA valuation settings specify that the NPV is to be calculated based on forward points. This would enable to calculate the NPV and perform valuation against the NPV. You will have to do NPV calculation in TPM60 prior to running TPM1.
As a second step, you can have swap accrual which will result in two postings - valuation based on NPV and then swap accrual.
