accounting, material ledger, special purpose ledger.
Define the standard/company currency before starting production. Choose
the currency in which the head office of your company or concern
creates the closing.

from USD to DEM, amounts stored on the database are interpreted as DEM
amounts and not as USD amounts. This could have a catastropic effect on
the values in the company currency.

this could result in incorrect amounts for the company currency or in
error messages in a number of transactions.
