Conversion rules

This chapter describes the conversion rules, or conversion functions that are used to convert these types of fields during currency initialization:

• Currency fields
• Amount fields
• Rate fields
• Rate factor fields
• Rate determiner fields

The currency system to which you convert determines the way in which the data is registered after the conversion. After currency initialization the registered data must be consistent in all its internal relations. Therefore, the method of data conversion depends on the currency system to which you convert.

Currency initialization does not affect data that needs not to be converted. Therefore, LN also determines whether data conversion is necessary when you change your home currencies.

For example, if reporting currency 1 before the conversion is reporting currency 2 after the conversion, the amounts and currency rates in reporting currency 1 are copied to the positions of the reporting currency 2 in the database. There is no need to recalculate the amounts or the rates.

For fields that cannot be converted by one of the standard CRI conversion rules, additional DLLs deal with the specific CRI requirements.
