The manual transaction cost = 457.03
The financial plan cost = 309.96 JPY
Why is there a discrepancy?
In an example use case,
A transaction is in example currency USD,
however the project currency is a different currency, e.g. JPY.
the transaction was performed in currency = AUD and was converted on the investment currency view.
If the manual transaction is incorrect, perform a WIP Adjustment on the transaction by just changing the currency.
