currency key
Component of a structure defined in ABAP Dictionary or a database table of type CUKY. A currency key can be associated with a currency field of a structure or database table. The currency key contains a currency ID from the database table TCURC, and defines the currency for the currency field. By default, the number of decimal places for a currency is always two. Currencies with a different number of decimal places must also be entered in the table TCURX, where the number of decimal places can be defined explicitly.
