Rounding Issue in PRC Draft Invoice where invoice currency is different then functional currency

Hello,

We are seeing rounding issue against project invoices where invoice currency(foreign) is different then project functional currency.

Project Functional Currency for the Ledger is  USD

Invoice currency & Customer Level currency is SGD

Example : - Invoice for 14139 SGD is submitted, The PRC Draft invoice generates project invoice as 14139.01 / 14138.99 SGD.

The invoice by bill transaction currency flag is not setup at project template level and thus is not enabled at project level. We have projects in PRODUCTION where this flag needs to be enabled at Project Level. System does not allow to enable this flag if there is base line funding/ events/EIs. Has anyone encountered with such issue and how was this addressed.
