Conversion rule for rate determiner

Rate determiner conversion-rule

A rate determiner defines the currency differences that will be written off as a result of currency rate fluctuation between the invoice date and the payment date.

Rate determiners vary per currency system. LN supports three types of handling currency differences:

These rate determiners exclude the home currencies from currency-difference calculations:
- Fixed Local
- Fixed Hard
- Fixed Local and Hard
These rate determiners use a specific exchange rate date for currency-difference calculations:
- Delivery Date
- Receipt Date
- Document Date
- Expected Cash Date
The Manually Entered rate determiner uses manually entered rates for currency-difference calculations

Some rate determiners cannot be used in specific currency systems. If the currency system changes and the rate determiner cannot be used in the new currency system, the rate determiner is changed to the most similar rate determiner that can be used in the new currency system. If the rate determiner can be used in the new currency system, it is not changed.

This table shows the rate determiners that can be used for the Standard, Single, Dependent, and Independent currency systems.

Rate determiner	Standard	Single	Dependent	Independent
Fixed Local	-	-	‑	Y
Fixed Hard	-	‑	-	Y
Fixed Local and Hard	-	‑	‑	Y
Delivery Date	-	Y	Y	Y
Receipt Date	-	Y	Y	Y
Document Date	Y	Y	Y	Y
Expected Cash Date	-	Y	Y	Y
Manually Entered	Y	Y	Y	Y
Fixed		Y	Y

Where:

Y = the determiner is valid for the currency system

‑ = the determiner is not not valid for the currency system

Rate-determiner conversion

If the previous rate determiner cannot be used in the new currency system, the rate determiner is converted. Rate determiners that can be used by the currency system before and after the currency initialization are not changed.

This table shows the rate determiners that are replaced during each currency initialization scenario.

Scenario	Before conversion	After conversion
Any to Standard	Fixed, Fixed Local, Fixed Local and Hard	Delivery Date, Expected Cash Date, Receipt Date, Fixed Hard, Document Date
Single to Dependent and Dependent to Single	Fixed Local and Hard, Fixed Local, Fixed Hard	Fixed
Single to Independent	Fixed	Fixed Local and Hard
Independent to Single	Fixed Hard, Fixed Local and Hard	Fixed Local, Document Date
