Procedure
You need to convert the limits manually and keep a record of the effective period.
Conversion of the Currency Key
The following two cases can apply:
a) The currency is not a limit characteristic. In this case, the currency is determined via the client and company code. The system carries out the conversion automatically using report program SEUVTBLV.
b) The currency is a limit characteristic. In this case, you need to set the currency field to ready for input (standard Customizing) and assign the currency key manually.
You can convert limits either before or after the local currency changeover.
