Home Currency = "RM"

Invoice Currency = "RM"
Amount = 45098.38
Amount in Invoice Currency = 45098.38
Amount in Home Currency = 45098.38

Receipt Currency = "RM"
Amount = -45098.38
Amount in Invoice Currency = -45098.38
Amount in Home Currency = -45098.38
Currency Differences = -2273.87

May I know where does the currency differences generated from since invoice and receipt were in same currency.

It caused the invoice 'consider' outstanding in the Open Entries Report and Customer Aging report

How many home currencies have you defined in your system? Rates for other home currencies could be different for the invoice date and the receipt date.

Only 1 home currency is defined.

I checked tfacr200, I notice that invoice was created with currency differences.

Thanks
