transaction-related actual postings, the system defaults this currency
as the transaction currency. Otherwise, the system defaults the
controlling area currency.

System Response

yet been entered.

How to fix this error?

desired currency under "Transaction currency" The system keeps this
currency during logon as the default value for transaction-related
actual postings.
To specify the currency for the longer term, save the desired currency
under user parameter "FWB" in the user master.
If you have already entered items for the document, you should post the
document, or delete the items, so that you can make an entry under
"Transaction currency".
